Passing parameters or information

Procedure 1: /GET-IDOM-LIBRARY-NAME LOGICAL-ID='SYSSPR',/ INT-LIB=IDOM-GLB-SYSSPR	Procedure 1: /ASSIGN-STREAM SYSINF,/ TO=*VAR(VAR-NAME=INT-LIB-NAME) /GET-IDOM-LIBRARY-NAME LOGICAL-ID='SYSSPR' /ASSIGN-STREAM SYSINF,TO=*SAME /IDOM-GLB-SYSSPR=INT-LIB-NAME#1.NAME
Procedure 2 for implementing the command GET-IDOM-LIBRARY-NAME: / . . . /DECLARE-PARAMETER INT-LIB(TYPE=*STRING,/ TRANSFER-TYPE=*BY-REFERENCE) . . . /INT-LIB = 'xxx'	Procedure 2 for implementing the command GET-IDOM-LIBRARY-NAME: /INT-LIB.NAME='xxx' /TRANSMIT-BY-STREAM STREAM-NAME=SYSINF,/ VAR-NAME=INT-LIB,/ RETURN-VAR=*NONE

If output information is to be returned in variables by a procedure that is called with CALL-PROCEDURE (directly or as an implemented procedure like in the example), then the following parameter declaration should be used:

/DECLARE-PARAMETER <var-name>,(...,TRANSFER-TYPE-*BY-REFERENCE)

This declaration is the best way to exchange information for simple variables (type ANY, STRING, INTEGER or BOOLEAN), in contrast to the use of variable streams as shown in the example on the right).
