CALL (E) | Program name | Plist name | _ | ER | LR |
The CALL operation passes control to the program specified in factor 2.
Factor 2 must contain a character entry specifying the name of the program to be called.
In the result field, specify parameters in one of the following
ways:
- Enter the name of a PLIST
- Leave the result field blank. This is valid if the called program does not access parameters or if the PARM statements directly follow the CALL operation.
Positions 71 and 72 must be blank.
To handle CALL exceptions (program status codes 202, 211, or 231), either the operation code extender 'E' or an error indicator ER can be specified, but not both. For more information on error handling, see Program Exception/Errors.
Any valid resulting indicator can
be specified in positions 75 and 76 to be set on if the called program
is an RPG program or cycle-main procedure that returns with
the LR indicator on.
Note: The LR indicator is not allowed
in a thread-safe environment.
