An experienced Macro Scheduler scripter was recently trying to figure out why the following code wasn’t doing what he expected:
If>seg_1=05
Let>monLtr=mm
Endif
Apparantly monLtr was always being set to 05. This told me that “mm” must have been a variable which had earlier been set to 05. But my friend said “I’ve looked all through the code I can’t see where “mm” is set anywhere”.
Then I reminded him of the Variable Explorer. “The what?” he asked.
Under the editor select Tools/Variable Explorer or hit Ctrl-Alt-V and you’ll get a box like this one. It shows a list of all the variables created by your script.
Bingo! There’s mm. Expand it and you’ll see all the lines where it is set/created. In this case it’s created on line 40 by the Min command.
In a long script it’s easy not to see the obvious. The Variable Explorer makes it easier.
Of course, it would also be sensible to use a better naming convention for the variable to avoid such confusion. Or use VAREXPLICIT or he could have used {“mm”} to specify the literal string value. But don’t forget the Variable Explorer as it can save a lot of hunting around.
