Parameters

The parameters are explained as follows:

name

An optional symbol, starting in column 1, that is the name on the IWMGCORF macro invocation. The name must conform to the rules for an ordinary assembler language symbol.

,ASYNC_FLAG=async_flag

An optional output parameter, which receives the indication whether or not the asynchronous flow flag is set. A value of 1 is returned, if the asynchronous flow flag is set. Otherwise 0 is returned. The caller must initialize the ASYNC_FLAG field before issuing the macro because IWMGCORF will not modify it if the EWLM_CORR field contains an invalid ARM correlator.

To code: Specify the RS-type address, or address in register (2)-(12), of a fullword field.

EWLM_CORR=ewlm_corr

A required input parameter, which contains an EWLM correlator. If the correlator is invalid (the architected length in the first two bytes is less than 4 or greater than 512), a call to this macro acts as a no-operation and no change to the ASYNC_FLAG or INDEP_FLAG is made.

To code: Specify the RS-type address, or address in register (2)-(12), of a character field.

,INDEP_FLAG=indep_flag

An optional output parameter, which receives the indication whether or not the independent flag is set. A value of 1 is returned, if the independent flag is set. Otherwise 0 is returned. The caller must initialize the INDEP_FLAG field before issuing the macro because IWMGCORF will not modify it if the EWLM_CORR field contains an invalid ARM correlator.

To code: Specify the RS-type address, or address in register (2)-(12), of a fullword field.
