BTU (Batch Template Update)

Purpose

Use this utility to:

• Update one or more templates.
• Create new templates based upon existing templates.

Usage notes

• You can filter the templates selected for processing by providing copybook member names or member masks so that only templates referencing such copybooks are updated.

INPUT=ddname

This points to the input DD name which can have one or more associated data sets that must be valid template data sets. If you do not specify INPUT or DSN parameters, then the DD DDIN is used as a default DD name for the input data sets. You can specify concatenated data sets. If an output data set is not provided, the template is updated in the data set from which it originated.

DSNIN=dsname

Data set name where templates reside.

MEMBER=member_in

The name of a single member in a PDS, or a member name pattern representing one or more members in a PDS to be processed.

A member name pattern can consist of any characters that are valid in a member name and two special pattern characters: the asterisk (*) and the percent symbol (%).

*

represents any number of characters. As many asterisks as required can appear anywhere in a member name pattern. For example, if you enter a member name pattern of *d*, all members in the PDS whose name contains “d” are processed.

%

is a place holding character that means a single character. As many percent symbols as necessary can appear anywhere in a member name pattern. For example, if you enter a member name pattern of %%%%, all members in the PDS whose name is four characters in length are processed.

member_in is ignored if the data set is not a PDS.

MEMSTART=startstring

Is used to specify the start of a range of member names to be included. If MEMSTART is specified but MEMEND is omitted, all members of the PDS(E) from the startstring value onwards are included. startstring can have the same values, including wild cards, as for the member-in parameter of the MEMBER keyword.

MEMEND=endstring

Is used to specify the end of a range of member names to be included. If MEMEND is specified but MEMSTART is omitted, all members of the PDS(E) up to the endstring value onwards are included. endstring can have the same values, including wild cards, as for the member_in parameter of the MEMBER keyword.

XMEMBERS

Provides a way to exclude from processing library members that would otherwise be selected using the MEMSTART, MEMEND, and MEMBER options.

xmem_filter

A member name filter identifying one or more members that are to be excluded from processing. A filter can be a member name pattern representing multiple members.

To specify a member name filter containing lowercase characters, use a character string in the format c'string'. Filter values can also be specified as hexadecimal strings in the format x'hex-digits'.

COPYBOOK

Allows you to specify a list of member names or patterns used to filter so that only templates referencing those copybooks, or copybooks that match the patterns, are selected for processing.

member_n

The name of the member to be processed. Generic name masks are not allowed.

LIBLIST

Allows you to specify a list of up to twelve data set names used to replace the copybook library lists in the selected templates.

dsn_n

The name of the data set name to be processed. Generic name masks are not allowed.

MEMLIST

Allows you to specify a list of member names with optional associated output template names. If you do not specify the associated template name, File Manager uses the copybook name or the name as identified by the MEMOUT mask, memmask.

member_n

The name of the member to be processed. Generic name masks are allowed.

template_n

The name of the template after it has been copied to the output data set. If unspecified, the output template is not renamed.

OUTPUT=ddname

Identifies the DD card which points to the template data set in which the templates are stored or replaced. It must refer to a PDS, PDSE, or sequential data set. Concatenated data sets are not supported.

DSNOUT=dsname

Defines the data set name where templates are created. It must be a PDS, PDSE, or sequential data set. You can further describe this data set, as follows:

(member-out)

Where DSNOUT=dsname specifies a PDS and you want to send the output to a specific member within this data set, this defines the output member name.

MEMOUT=memmask

Where a number of input members have been specified, you can specify a member name pattern for the output templates, allowing you to rename your templates as they are created. The member name pattern can consist of any characters that are valid in a member name and two special pattern characters: the asterisk (*) and percent sign (%).

Asterisk (*)

The asterisk is a place-holding character that means multiple characters with no change. Only one asterisk should appear in the mask. Any subsequent asterisk characters are treated as percent signs. For example, if you enter:

ABC*

The renamed members all begin with ABC followed by the remainder of the old member name.

Percent sign (%)

The percent sign is a place-holding character that means a single character with no change. As many percent symbols as necessary may appear anywhere in a member name. For example, if you enter:

%%%A*

The 1st 3 characters of the renamed members remain unchanged, the 4th character is replaced with the letter “A” and the remainder of the old member name remains unchanged.

REPLACE

Specifies whether or not File Manager replaces like-named templates in an output partitioned data set.

NO

Like-named templates in the output partitioned data set are not replaced.

YES

Like-named templates in the output partitioned data set are replaced.

NOUPDATE

Specifies whether or not File Manager writes back updates to the data set.

NO

Updates are written back to the data set.

YES

Updates are not written back to the data set.

OVERRIDE

Specifies whether or not File Manager overrides any compile options found in the template with the compiler options found specified in the parameter list.

NO

Compile options found in the template are not overwritten with the compiler options found specified in the parameter list.

YES

Compile options found in the template are overwritten with the compiler options found specified in the parameter list.

PRESERVE

Specifies whether or not File Manager uses the current version of the copybook.

NO

File Manager searches for the first version of the copybook.

YES

File Manager uses the current version of the cookbook, provided the copybook still exists in the library it was previously found in, and the library is in the list the update process is using.

File Manager searches for the first version of the copybook in the order the libraries are listed if one of these conditions applies:

• NO has been specified for this option.
• The copybook no longer exists in the library it was previously found in.
• The library is not in the list the update process is using.

Compiler options

If you specify OVERRIDE=YES, then the specified compile options shown here override the options found in the template:

LANG

Determines whether File Manager automatically detects the copybook language or interprets the language as COBOL, PL/I, or HLASM.

AUTO

Automatically detect whether the copybook language is COBOL or PL/I, and invoke the appropriate compiler. If the compilation results in a return code greater than 4, then invoke the compiler for the other language. If the second compilation also results in a return code greater than 4, then retry the first compiler and report the compilation errors. If File Manager successfully creates a template (despite the compilation errors), then continue processing with the template.

COBOL

Invoke the COBOL compiler to create a template from the copybook. (Do not invoke the PL/I compiler, even if the COBOL compilation results in errors.)

PLI

Invoke the PL/I compiler to create a template from the copybook. (Do not invoke the COBOL compiler, even if the PL/I compilation results in errors.)

HLASM

Invoke the HLASM compiler to create a template from the copybook.

COBOL options

The following options are used to compile a COBOL copybook into a template:

DBCS=YES

Use the DBCS compiler option.

DBCS=NO

Use the NODBCS compiler option.

For details on the effect of the DBCS and NODBCS compiler options, see the IBM COBOL Programming Guide for OS/390 & VM.

CDPC=NO

Do not use the COBOL SPECIAL-NAMES paragraph "Decimal-point is comma".

CDPC = YES

Use the COBOL SPECIAL-NAMES paragraph "Decimal-point is comma".

CAE=NO

Do not use the COBOL compile option ARITH(EXTEND).

CAE = YES

Use the COBOL compile option ARITH(EXTEND).

MIXED = NO

Field names stored in the template in uppercase.

MIXED = NO

Field names stored in the template in uppercase.

MIXED = YES

Field names stored in the template in the original case as coded in the COBOL copybook.

RFROM1 RTO1 … RFROM5 RTO5

Up to five pairs of “From” and “To” pseudo-text character strings for the COBOL REPLACE compiler-directing statement.

If your COBOL copybooks contain characters that you want to remove or replace with other characters before compiling the copybooks into templates, then use these replacing options.

For example, if your copybooks contain colon characters (:) that you want to remove before compiling, then specify '==:==' as operand1 and '=====' as operand2.

For details on specifying “From” and “To” strings for COBOL REPLACE, see the IBM COBOL Language Reference.

COMPMAXRC

Sets the maximum acceptable return code for a copybook compile. A return code higher than the specified level causes the function to stop. Default is 4.

PL/I options

The following options are used to compile a PL/I copybook into a template:

BIN63=YES

Use the LIMITS(FIXEDBIN(63)) compiler option.

BIN63=NO

Use the LIMITS(FIXEDBIN(31)) compiler option.

DEC31=YES

Use the LIMITS(FIXEDDEC(31)) compiler option.

DEC31=NO

Use the LIMITS(FIXEDDEC(15)) compiler option.

GRAPHIC=YES

Use the GRAPHIC compiler option.

GRAPHIC=NO

Use the NOGRAPHIC compiler option.

UNALIGNED=YES

Use the DEFAULT RANGE (*) UNALIGNED, language statement to change the default alignment.

UNALIGNED=NO

Use the PL/I default.

COMPMAXRC

Sets the maximum acceptable return code for a copybook compile. A return code higher than the specified level causes the function to stop. Default is 4.

For details on the effect of these compiler options, see the IBM VisualAge PL/I for OS/390 Programming Guide.

HLASM options

The following options are used to compile a HLASM copybook into a template:

DBCS=YES

Use the DBCS compiler option.

DBCS=NO

Use the NODBCS compiler option.

NOALIGN=YES

Use the NOALIGN compiler option.

NOALIGN=NO

Use the ALIGN compiler option.

COMPMAXRC

Sets the maximum acceptable return code for a copybook compile. A return code higher than the specified level causes the function to stop. Default is 4.

For details on the effect of these compiler options, see the HLASM V1R6 Programmer's Guide.
