When the selected field is alphanumeric, the fields on the Field Attributes panel are:

Fixed attributes

Shows the fixed attributes of the field, such as field name, type, and length, and the starting position, relative to zero, of the field within the record.

These attributes are determined by copybook definitions or by the user-defined attributes in a dynamic template.

Use attributes

Used to specify certain display (or print) attributes used by edit, view, and print functions. For alphanumeric fields, the available use attributes are:

Output width

Number of character positions used by edit, view, compare and print functions to show this field in TABL display or print format. For alphanumeric fields, this value can range from 6 to either 30 or the field width + 10 (whichever is the greater).

The default output width is the maximum of the number of characters needed to show the field heading (or field name, if no heading is specified), and the number of characters needed to show the value of the field.

Heading

The alternate heading that replaces the field name on displays and reports.

CCSID

Specifies the CCSID to be associated with this field.

Length Field

Only shows for a segmented template and alphanumeric fields whose length does not exceed 4.

Each layout can have one field flagged as a length field. This tells File Manager to calculate the segment length based upon the value contained in the field.

You can enter one of the following values:

blank

This is not a length field.

1

The field value is the segment length.

2

The field value, plus the length of the field, is the segment length.

If a length field is not provided, the segment length is taken to be the 01 field length.

Create attributes

These define the field-specific attributes used by the data create functions when creating test data for records containing this field.

Filler

Specifies a value that is to be placed in each byte of the field before any other operation in the construction of the field. Can be one of:

char

A character such as 0 to be written in each byte.

X'cc'

A hexadecimal value, such as X'FF' to be written in each byte.

Default value is blank.

Action

Specifies how the contents of the field are to be varied for each record. Can be one of:

FX

The contents of the field are to remain fixed.

RA

The contents of the field are to be generated from characters selected at random from the specified pattern. A different set of characters is selected for each record.

RO

The contents of the field are to be rolled. The pattern you specify is shifted left one byte for each record until the first non-blank character of the pattern is in the first byte of the field. Then, the pattern is shifted right one byte for each output record until it returns to its original position in the field. RO can only be used with a user-supplied pattern, not with an IBM®-supplied pattern.

The pattern must start with a blank, or the result is the same as FX. The roll only occurs within the length of the pattern.

RP

The contents of the field are to be rippled. The pattern you specify is shifted left one byte for each record and the truncated character is appended to the right hand end of the pattern.

SL

The contents of the field are to be shifted left for each record. The pattern you specify is shifted left one character and filled to the right with a space. When all characters in the pattern have been shifted out, the original pattern is restored and the process is repeated.

SR

The contents of the field are to be shifted right for each record. The pattern you specify is shifted right one character and filled to the left with a space. When all characters in the pattern have been shifted out, the original pattern is restored and the process is repeated.

TL

The contents of the field are to be truncated on the left for each record. The pattern you specify is left truncated (the leftmost character replaced with a space) one character at a time until all characters in the pattern have been truncated. Then, the original pattern is restored and the process is repeated.

TR

The contents of the field are to be truncated on the right for each record. The pattern you specify is right truncated (the rightmost character replaced with a space) one character at a time until all characters in the pattern have been truncated. Then, the original pattern is restored and the process is repeated.

WV

The contents of the field are to be waved. The pattern you specify is shifted left one byte for each record until the first non-blank character of the pattern is in the first byte of the field. Then, the original pattern is restored and the process repeated. WV can only be used with a user-supplied pattern, not with an IBM®-supplied pattern.

The pattern must start with a blank, or the result is the same as FX. The roll only occurs within the length of the pattern.

Start character

Sets the starting character to be used when you specify an IBM®-supplied pattern (AL, AN, or CO) or a user-supplied pattern (with the exception of RO, WV, and FX). The specified character must be one of the characters in the IBM®-supplied pattern or user-supplied pattern.

Default: First character in IBM®-supplied pattern or user-supplied pattern.

Pattern

Specifies the pattern to be used when generating data for this field. You can specify either an IBM®-supplied pattern indicator or a user-supplied pattern. The user-supplied pattern can be either a character string or a hexadecimal string. A character string must be enclosed in quotation marks, while a hexadecimal string must be enclosed in quotation marks and be preceded by a X. The hexadecimal string must contain an even number of valid hexadecimal characters. The IBM®-supplied patterns you can specify are:

AL

Alphabetic - characters A-Z, inclusive.

AN

Alphanumeric - characters A-Z, 0-9 inclusive.

AX

Alphanumeric displayed in long hexadecimal.

CO

Collating sequence - all printable characters in the range X'40' - X'F9'.

If you provide a user-supplied pattern that is longer than the field, for actions other than RA and RP the pattern is first truncated on the right to fit the receiving field before the specified action is performed. For the RA action, characters are randomly selected from the entire user-supplied pattern. For the RP action, the entire pattern is rippled for each record before it is truncated to fit the receiving field. If you provide a user-supplied pattern that is shorter than the field, you can specify that you want the pattern to be repeated to fill the field.

Default: None

Repeat user pattern

Specify YES if you have provided a user-supplied pattern that is shorter than this field and you want the pattern to be repeated as many times as necessary to fill the field. By default, File Manager uses the fill character to pad the receiving field when the user-supplied pattern is shorter than the field. This option has no effect when the RA action is specified.

Note: IBM®-supplied patterns are always repeated in a field, as necessary.

Default: NO

Scrambling Options

These options control field scrambling used during a copy function to produce test data.

Scramble Type

Specify one of the following values:

Blank

No scrambling is performed. Value or range specifications are saved but ignored for the associated function.

1 (Random)

Performs random scrambling. The same input value produces different output values on subsequent invocations.

2 (Repeatable)

Performs repeatable scrambling. The same input value produces the same output value on subsequent invocations.

3 (Translate)

Performs translation. The value data set is searched to find a matching input value. If a match is found, then the output value is taken from the output column of the matching record.

4 (Exit)

Invokes a scrambling user exit. File Manager displays a panel where you can specify the user exit name and user exit parameters and options.

5 (ODPP)

Performs data scrambling by using the ODPP command that is specified in the adjacent command field. This is the Optim Data Privacy Provider command input area. The Col field is the left column position, which can be used to position to the error column when a syntax error occurs. Refer to the ODPP Syntax Guide for the command syntax. The ODPP Command is a scrollable field. Use the F10 and F11 keys to scroll left and right. Use the F4 key to expand the command into a separate window. This option is only available if File Manager was customized to access ODPP, and the environment is successfully initialized. For more information, see the File Manager Customization Guide.

Value

Select this option to provide values for the output field. The associated fields (Column In, Out and Dsn), in conjunction with the Scramble Type, determine the output value.

Column In

Defines the start location of the input field value on the value data set, and is used when the translate process is run during a copy operation to match the input field with a value on the value data set. The length of the field is set to the length of the input field that is mapped to this field during the copy process.

Note: This value is only required when you select the scramble type, Translate.

(Column) Out

Defines the start location of the output field value on the value data set, and is used as follows during a copy operation:

• For scramble type, Translate: If an input field value is matched on the value data set, then the corresponding output value is used.
• For scramble types, Random or Repeatable: The input value is used to randomly or repeatably select an output value from the value data set.

The length of the field is the current field length as displayed on this panel.

Note: This value is required when you select the scramble type, Translate. If you select Random or Repeatable, and also select Value, then the start location defaults to 1 if a value data set name (Dsn) has been provided.

Dsn

Defines the value data set. It can be any catalogued sequential, partitioned or VSAM data set containing data that is used to determine the output field value during a copy process.

When specifying the data set name, the following rules apply:

• In a generic data set name, use the percent sign (%) to represent a single character, and an asterisk (*) to represent any number of characters within one qualifier. Two asterisks (**) represent any number of characters within any number of qualifiers.
• The TSO prefix (as defined for your user ID) is used as the high-level qualifier for any name that is not enclosed in quotation marks.
• For performance reasons, you should qualify the data set name as much as you can.
• If the data set is partitioned, then you can provide a member name in the form dsn(member). If you do not provide a member name, or you provide a generic member name, then a member selection list is displayed for you to select a member.
