Table 1. Bypassing or Execution
of Current Step Based on COND Parameter
Test in COND parameter
Return
Code (RC) from a previous step
Bypass current step
Execute current step
COND=(code,GT)
code <= RC
code > RC
COND=(code,GE)
code < RC
code >= RC
COND=(code,EQ)
code ^= RC
code = RC
COND=(code,LT)
code >= RC
code < RC
COND=(code,LE)
code RC
code <= RC
COND=(code,NE)
code = RC
code ^= RC
Note: When the COND parameter does not name a previous step, the system
tests all previous steps. If any test is satisfied, the system bypasses
the current step.

ONLY Subparameters on Step Execution
