DSE (Data Set Edit)

Purpose

The DSE function displays the Data Set Edit or Edit Entry panel, in online mode. This function can be invoked from a REXX program or a TSO clist or entered on an ISPF Command line, but cannot be used in batch jobs as it is an interactive function.

Usage notes

When invoked from an ISPF Command line without a parameter, the Data Set Edit Entry panel is displayed in interactive mode and you can specify a valid data set for browsing. If you include a valid data set name as a parameter, then you bypass the Entry panel, and go directly to editing the specified data set.

When invoked from a REXX procedure or TSO list, you must supply the data set name.

DSNIN=dsname

Defines the name of the data set to be edited. If any DD statements are specified, they are not used. The name may include a member name in parenthesis. If the member is specified here, the associated Member parameter must be empty. Must be specified when $DSE is invoked from a REXX procedure or TSO clist.

Can be omitted when DSE is entered on a command line. If specified, you bypass the Entry panel, and go directly to the Data Set Edit panel. When omitted, the Data Set Edit Entry panel is displayed in interactive mode and you can specify a valid data set for browsing.

You can further describe this data set, as follows:

MEMBER=member

The name of a single member in a PDS, or a member name pattern representing one or more members in a PDS. If the data set is a PDS, you must specify this parameter.

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=member is ignored if the data set is not a PDS.

MQ:manager:queuename

You can specify a MQ queue in place of a data set name, where:

manager: The MQ manager to be used. If you specify a generic name, File Manager displays a list of matching managers to select from.
queuename: The queue to be used. If you specify a generic name, File Manager displays a list of matching queues to select from.

rt:applid:rname

You can specify a CICS® resource in place of a data set name, where:

rt

Resource type. Valid values are:

FI: For a CICS® file.
TD: For a Transient Data Queue.
TS: For a Temporary Storage Queue.

applid

The VTAM® applid of the CICS® system.

rname

The name of the resource.

VOLSERIN=volser

Volume serial number for a non-cataloged data set.

POSITION=skip

Number of logical records to be skipped from the beginning of the data set. The default is 0.

KEY=key (VSAM only)

A key for KSDS records, or a slot number for RRDS records. The maximum key length is 30 characters. The first record with a key or slot value greater than or equal to key is the first record copied. If you omit the key and skip values, browsing begins with the first record in the data set.

If the key contains lowercase characters, blanks, or commas, enclose it in quotation marks. You can also specify a key in hexadecimal format (for example, X'C1C2C3').

TCIN=tcin(member)

PDS and member name of the copybook or template that describes the record structure of your data set.

OFFSETIN

The length of the 01 field in the template and the start locations of the fields within that 01 field are adjusted by the value provided.

value: The offset value, which must be in the range -32760 to 32760, to be applied to the corresponding field identifier. If no field identifier is supplied and ALL is not used, the value is applied to the first Level 01 field in the template.
ALL: Where the template contains multiple record structures, this keyword applies the corresponding value to all Level 01 within the template.
Note: You can specify a value for ALL and then override this value for individual layouts by providing subsequent value and fieldname combinations.
fieldname: The name of the Level 01 field to which value is to be applied. The default is the first Level 01 field in the template.

Copybook processing

If you specify a copybook (instead of an existing template), File Manager uses these processing options to compile the copybook into a template:

LANG

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

Note: The COMPLANG setting in FMN0POPT is the equivalent of the LANG parameter in batch functions.

If COMPLANG is set it determines the installation default language for online and batch compilation.
If COMPLANG is not specified then COBOL is the installation default for online compilation and AUTO is the default for batch compilation.
If a value of COBOL, HLASM, PL/1, or AUTO is specified (in the Compiler Language Selection panel or through the LANG parameter in a batch job) it overrides the default language.

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.

DSINFO

Specifies whether additional data set information for input and output sources should be produced in batch reports for the DSP, DSM, DSC, and FCH commands.

NO: No additional data set information is generated.
YES: Generates data set information including DSORG, RECFM, LRECL, BLKSIZE, and VSAM attributes including average record length, maximum record length, key offset, key length and reuse, for input and output data sets when applicable.

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 = 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.

CBLMAXRC

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.

Note: The COMPMAXRC parameter is still supported but it is recommended that the CBLMAXRC parameter is used instead. If you do specify the COMPMAXRC parameter, it takes precedence over the language MAXRC.

CBLLIBS

Allows you to specify a list of up to ten data set names to be specified in the SYSLIB concatenation list. These data sets are searched in the order specified for COPY and INCLUDE members for the compilation.

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

CBLADDOP

Additional COBOL compiler options which are included in a CBL statement when compiling COBOL copybooks.

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.

PLIMAXRC

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.

Note: The COMPMAXRC parameter is still supported but it is recommended that the PLIMAXRC parameter is used instead. If you do specify the COMPMAXRC parameter, it takes precedence over the language MAXRC.

PLILIBS

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

PLIADDOP

Additional PL/I compiler options which are included in a *PROCESS statement when compiling PL/I copybooks.

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.

ASMMAXRC

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.

Note: The COMPMAXRC parameter is still supported but it is recommended that the ASMMAXRC parameter is used instead. If you do specify the COMPMAXRC parameter, it takes precedence over the language MAXRC.

ASMLIBS

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

ASMADDOP

Additional HLASM compiler options which are included in a *PROCESS statement when compiling COPY and MACRO members.
