CRTCLS and CHGCLS command changes

Create Class (CRTCLS) and the Change Class (CHGCLS) MAXTMPSTG parameter changes.

The Create Class (CRTCLS) and the Change Class (CHGCLS) commands have changed so that the MAXTMPSTG parameter is specified in megabytes. Any class object (*CLS) on the system already stores this value in megabytes (or has *NOMAX), so the objects continue to work exactly like they did before. Stored CL command source, however, is affected. If you have a CL command that specifies the value in kilobytes, you need to change the source code to specify the value in megabytes.
