Parameters

The parameters are explained as follows:

name

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

EWLM_CORR=ewlm_corr

A required input/output parameter, which contains an EWLM (ARM) correlator. If the correlator is invalid (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 EWLM_CORR field is made.

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

,RETCODE=retcode

An optional output parameter into which the return code is to be copied from GPR 15. If you specify 15, GPR15, REG15, or R15 (within or without parentheses), the value will be left in GPR 15.

To code: Specify the RS-type address of a fullword field, or register (2)-(12) or (15), (GPR15), (REG15), or (R15).

,RSNCODE=rsncode

An optional output parameter into which the reason code is to be copied from GPR 0. If you specify 0, 00, GPR0, GPR00, REG0, REG00, or R0 (within or without parentheses), the value will be left in GPR 0.

To code: Specify the RS-type address of a fullword field, or register (0) or (2)-(12), (00), (GPR0), (GPR00), REG0), (REG00), or (R0).

,SET_ASYNC_FLAG=NO_SET_ASYNC

,SET_ASYNC_FLAG=OFF

,SET_ASYNC_FLAG=ON

An optional parameter, which requests to update the asynchronous flow flag. The default is SET_ASYNC_FLAG=NO_SET_ASYNC.

,SET_ASYNC_FLAG=NO_SET_ASYNC

indicates that parameter SET_ASYNC_FLAG has not been specified and the asynchronous flow flag in the EWLM correlator will not be changed.

,SET_ASYNC_FLAG=OFF

requests to clear the asynchronous flow flag. The independent flag is also cleared, since the independent flag may only be ON, if the asynchronous flag is ON.

,SET_ASYNC_FLAG=ON

requests to set the asynchronous flow flag to ON.

,SET_INDEP_FLAG=NO_SET_INDEP

,SET_INDEP_FLAG=OFF

,SET_INDEP_FLAG=ON

An optional parameter, which requests to update the independent flag. The default is SET_INDEP_FLAG=NO_SET_INDEP.

,SET_INDEP_FLAG=NO_SET_INDEP

indicates that parameter SET_INDEP_FLAG has not been specified and the independent flag in the EWLM correlator will not be changed.

,SET_INDEP_FLAG=OFF

requests to clear the independent flag.

,SET_INDEP_FLAG=ON

requests to set the independent flag to ON. The independent flag should be set only if the asynchronous flag is already set or will be set by this request.
