Parameters

SELMEMIF supports the following parameters:

field-name

Use field-name when referencing a data field that is defined in the record's layout. The use of field-name requires that the record's layout be available to the CA File Master Plus job step. For more information on how to make the record's layout available, see the keyword LAYOUTFILE.

Note: When this parameter is supplied, the keyword's position, length, decimal-positions, and data type (when supplied), are all retrieved from the field-name definition, and are used to validate the data's format.

position

The starting field positioning the record. Valid values are the following:

1–32760

The actual position number

+nnn or –nnn

The relative position to the record's current location

scan-length

The amount of data to compare. If zero, scanning is done starting at the position parameter value to the record length. Valid values are 0 – 32760. If the scan-length is omitted, no scanning is done.

operator

Valid choices include the following:

CO

Contains—If a field-name is supplied, the position and scan-length values are retrieved from the field-name's defined starting position and physical length. If position and scan-length are supplied, the record is scanned for the data beginning at position for a length of scan-length.

EQ

Equal

NE

Not equal

GT

Greater than

GE

Greater than or equal to

LE

Less than or equal to

LT

Less than

data

Valid choices include the following:

C'c…'

Character—matches specified case

N'n…'

Numeric—processes the literal as defined by the field-name parameter. You must define the field-name parameter as a numeric field, and it is only valid when you supply a field-name parameter.

P'n…'

Packed

T'x…'

Text—matches both lower and uppercase alphabetic characters. Alphanumeric characters are permitted.

X'hh…'

Hexadecimal

data–type

Valid choices include the following:

EQP

Valid packed decimal data

NEP

Not valid packed decimal data

EQN

Valid numeric data

NEN

Not valid numeric data

Example

This example command and keyword syntax copies the member if the first nine characters of any of the member's records begin with either the character string '//FMMVS31' or '//FMMVS41'. No other members are copied:

COPY,
  REPLACEMEM(Y),
  SELMEMIF(1,EQ,C'//FMMVS31'),
    OR(1,EQ,C'//FMMVS41')

An equivalent command follows:

COPY,
  REPLACEMEM(Y),
  SELMEMIF(1,EQ,C'//FMMVS31,//FMMVS41')
