Q about if statement

[ahasan]

Is there a hard rule about not changing control variables in if() statements?

The following code simplifies some Win32 programming, but not sure if I am creating problems:

if(bFlag) then ! bFlag is the ctl variable

bFlag = .FALSE.

Call Subroutine

bFlag = .TRUE.

end if

Thanks for any input.

No. That's perfectly acceptable. Note, however, that changing a DO-loop control variable inside the loop is not allowed.
