DISPLAY PSW<br />

Use DISPLAY PSW to see the program status word of your virtual machine.<br />

ALL<br />

displays the current values <strong>and</strong> interruption code information for the current<br />

PSW <strong>and</strong> all old <strong>and</strong> new interrupt PSWs (except RESTART).<br />

EXT<br />

SVC<br />

displays the current values <strong>and</strong> appropriate interruption code information for<br />

both the new <strong>and</strong> old PSWs specified—that is, external, SVC, program check,<br />

machine check, <strong>and</strong> I/O.<br />

1. The DISPLAY PSW comm<strong>and</strong> is valid for a z/Architecture virtual machine only if<br />

SET PSWTRANS (with ALL or DISPLAY option) has been issued previously.<br />

2. DISPLAY PSW ALL displays the PSW as a 128-bit PSW for z/Architecture<br />

virtual machines.<br />

3. For a z/Architecture virtual machine, the PSW is 128 bits to accommodate 64-bit<br />

instruction addresses. An exp<strong>and</strong>ed PSW is labeled in the comm<strong>and</strong> output as<br />

″PSWG″. The SET PSWTRANS comm<strong>and</strong> allows the PSWs from a<br />

z/Architecture virtual machine to be shown <strong>and</strong> manipulated in the 64-bit<br />

ESA/390 format.<br />

When the DISPLAY PSW comm<strong>and</strong> is issued from a z/Architecture virtual<br />

machine (with a previous SET PSWTRANS ALL/DISPLAY issued), the 128-bit<br />

z/Architecture format PSW must be converted to a 64-bit ESA/390 format PSW.<br />

This conversion is done as follows:<br />
