COLLECTDATA Statement

Retrieves data passed by the PASSDATA clause of a PERFORM statement.

Syntax

COLLECTDATA variable

Syntax Elements

variable is the name of the variable where the data is returned.

Operation

The COLLECTDATA statement is used in conjunction with the PERFORM statement. It is assumed that you are familiar with the operation of the PERFORM statement in this description.

The COLLECTDATA statement is only used in a program that has been PERFORMed by another program. The data returned to the variable is passed by the PASSDATA clause of the PERFORM statement. If no PASSDATA clause was used, then a value of null is assigned to the variable.

Comments

Use of the COLLECTDATA statement in a program that has not been PERFORMed is meaningless. In this case, the variable is assigned a null value.

Example

      PROG1

001 PERFORM 'RUN BP PROG2' PASSDATA 'ABC'

      PROG2

001 COLLECTDATA COLLVAR

002 PRINT 'PROG2: DATA=':COLLVAR
