You can also use conditional compilation so that the statement is included in the compile only if a particular constant is set in that configuration.
So if you used:
display "in test"
$if DEBUG = 1
call "CBL_DEBUGBREAK"
$end
display "after break"
accept any-key
goback.
And in your Debug Configuration you added the directive:
CONSTANT DEBUG(1)
And in your Release Configuration you added the directive:
CONSTANT DEBUG(0)
Then the statements between the $if and the $end would only be compiled when the debug configuration was in effect.
