address

The address at which IDF should stop. Supply the address as part of the command, or by the cursor position.

No exit routine processing is performed during, or at the completion of, the UNTIL command. As with MRUN or MSTEP, if the UNTIL command is issued within a macro, you must use EXTRACT EVENT to determine what type of event completed the command.

z/VM

If you issue UNTIL from within an IDF macro, you should make sure that it is issued through the LPSW Fastpath addressing environment. This is the default environment established when the IDF macro is entered. Using this interface eliminates any SVC linkages between REXX and IDF, so that IDF can provide optimum flexibility in what the target program can itself execute under UNTIL. See the usage notes under MRUN for further details.
