7.22 GET_RECORD_LENGTH | GET_RECORD_LENGTH2

When returning control to Extract or Replicat, user exits are responsible for setting the length of the target record if and when mapping occurs. Use GET_RECORD_LENGTH or GET_RECORD_LENGTH2 to obtain this value when the mapped record is not compressed. Set the EXIT-PARAMS structure member RECORD-LENGTH to this value.

GET_RECORD_LENGTH2 is only valid for use with records less than 32767. GET_RECORD_LENGTH2 is valid for both these smaller records and the longer records defined with DDL2.

Syntax GET_RECORD_LENGTH

For C:

#include "usrdecs"
short    record_length;
short    source_or_target;
short    result;
result = GET_RECORD_LENGTH (&record_length, source_or_target);

For TAL:

?source usrdect
int     result;
int     .ext record_length;
int     source_or_target;
result := GET_RECORD_LENGTH(record_length,  source_or_target);

For COBOL:

?CONSULT =EXTRACT (or =REPLICAT)
01 record-length    PIC S9(4) COMP.
01 source-or-target PIC S9(4) COMP.
01 result           PIC S9(4) COMP.
ENTER C "GET_RECORD_LENGTH" using record-length, source-or-target
         giving result.

record_length

record-length

The record length as calculated internally by Extract or Replicat.

source_or_target

source-or-target

Represented by either EXIT‐FN‐SOURCE‐VAL or EXIT-FN-TARGET-VAL to indicate whether to retrieve the source or target record.

result

A code indicating whether the call was successful or not.

Syntax GET_RECORD_LENGTH2

For C:

#include "usrdecs"
long    record_length;
short    source_or_target;
short    result;
result = GET_RECORD_LENGTH2 (&record_length, source_or_target);

For TAL:

?source usrdect
int     result;
int(32) .ext record_length;
int     source_or_target;
result := GET_RECORD_LENGTH2(record_length,  source_or_target);

For COBOL:

?CONSULT =EXTRACT (or =REPLICAT)
01 record-length    PIC S9(8) COMP.
01 source-or-target PIC S9(4) COMP.
01 result           PIC S9(4) COMP.
ENTER C "GET_RECORD_LENGTH2" using record-length, source-or-target
         giving result.

record_length

record-length

The record length as calculated internally by Extract or Replicat.

source_or_target

source-or-target

Represented by either EXIT‐FN‐SOURCE‐VAL or EXIT-FN-TARGET-VAL to indicate whether to retrieve the source or target record.

result

A code indicating whether the call was successful or not.
