&SYSJES

&SYSJES contains the name and the level of the JES installed. For example,

PROC 0
WRITE &SYSJES
EXIT

may return JES2 OS 2.10. In this example JES2 is the JES name and OS 2.10 is the JES level, representing version and release number of JES2. The JES level may contain a modification level as well.

The values returned are provided by the subsystem interface request routine (IEFSSREQ).

Both strings are separated by a blank character; any trailing blank characters are removed. If either the JES name or level returns an empty character string, then no separating blank character is inserted.

If the subsystem is not active the string -INACTIVE- is returned (note the string delimiters).

If the system finds that the subsystem is neither JES2 4.3 or later nor JES3 5.1.1 or later, the &SYSJES control variable contains the string -DOWNLEVEL- (note the string delimiters).
