Usage Notes for OPSWAIT

Keep these notes in mind when using OPSWAIT:

Do not use the OPSWAIT function in any type of rule other than an REQ rule. Using OPSWAIT in a TOD rule delays the execution of other TOD rules. The specification of OPSWAIT in any other type of rule is ignored.
When a particular operation (such as waiting) needs to be performed from an OPS/REXX program or rule, and the operation can be performed by either using a TSO command processor or by using an OPS/REXX function or host environment command, the OPS/REXX function or host environment command is always more efficient.
When the same operation is performed repeatedly, such as in a loop, the difference in CPU resources that are consumed can be significant.

For these reasons, we recommend that whenever it is possible, you should use the OPSWAIT function in OPS/REXX programs and REQ rules rather than the OPSWAIT TSO command processor.
