post a more meaningful snippet and You might get more explanations
even if Your sample does not make sense,
the analysis for the two lines posted is...
the JH variable is not initialized,
it will not match the comparison with one blank
it will not be set to the new value
the display of an un-initialized variable will just display its name
analysis confirmed by testing
WRONG code
| Code: |
/* rexx */
Trace "O"
if JH = ' ' then JH = '%%.'
say JH
exit |
formally correct code ( VARIABLES INITIALIZED)
| Code: |
/* rexx */
Trace "O"
JH = ' '
if JH = ' ' then JH = '%%.'
say JH
exit |
