It does indeed know that the variable has not changed.

Subject: Re: Guaranteeing re-resolution on CALL statements


If you make FOO a variable, it should re-resolve. But... I wonder if
the compiler is smart enough to know that the if the value being moved
to it is always the same (ex. "MYPGM") it may optimize it out?

I have a situation (in an update utility) in which a statement of the
form

C CALL FOO
C PARM BAR
. . .

is called repeatedly for different "elements" of the update. It can,
under certain circumstances, result in FOO itself being replaced,
producing a MCH3402 exception on subsequent iterations.

Anybody know of an easy way to guarantee re-resolution of FOO to the new

version, if it gets updated?
