Return Reason (Reason Code) Parameter

The return reason parameter for an OPENVM routine is a signed binary integer. To declare the return reason parameter, specify RTNR as the data type in the template file:
     RTNR    4    OUTPUT

The return reason parameter always has a data length of 4 bytes and a data direction of OUTPUT. You must specify the length and direction in the template.

In REXX, the data type is numeric character string. The REXX CSL interface converts the binary value on output back to a numeric character string.
