OPS/REXX Built-in Functions › OPSUSS Function › Entity Argument

Entity Argument

The entity must be a character string or integer number corresponding to the subfunction specified. The DUB and ALLDATA subfunction should have a null entity argument. The COMMAND, PATH, and JOBNAME subfunctions may be prefixed or suffixed with an '*' and may also contain the wildcard matching character '%' to match any character of the subfunction value retrieved. As a prefix, '*' specifies 'the value must end with' the entity value specified. As a suffix, '*' specifies 'the value must begin with' the entity value specified. '*' and '%' may be used alone or in combination.

For example, if OPSUSS('PROCESS','PATH','*/bin/%h' ) found a process whose path value was ' /user/bin/sh ' it would be selected as matching the subfunction entity whereas '/sbin/sh ' would not be selected.
