Result:

• The fully-qualified name is prefixed by the PREFIX and is suffixed by "exec" or "clist", unless the non-fully-qualified name already has the appropriate suffix.
• Procedure is run as the keyword specifies.

ex tools(mem1) exec

runs REXX exec "mem1" from: ‘slk27.tools.exec(mem1)’.

ex tools(mem2) clist

runs CLIST "mem2" from: ‘slk27.tools.clist(mem2)’.

ex tools.exec(mem1) exec

runs REXX exec "mem1" from: ‘slk27.tools.exec(mem1)’.

No need to add the "exec" suffix because the name already has the appropriate suffix.

ex tools.clist(mem2) clist

runs CLIST "mem2" from: ‘slk27.tools.clist(mem2)’.
