An experienced Macro Scheduler scripter was recently trying to figure out why the following code wasn’t doing what he expected:<\/p>\n

If>seg_1=05
\n\u00a0\u00a0Let>monLtr=mm
\nEndif<\/p>\n

Apparantly monLtr was always being set to 05. \u00a0This told me that “mm” must have been a variable which had earlier been set to 05. \u00a0 But my friend said “I’ve looked all through the code I can’t see where “mm” is set anywhere”. \u00a0<\/p>\n

Then I reminded him of the Variable Explorer. \u00a0“The what?” he asked.<\/p>\n

\"varexplorer\"Under the editor select Tools\/Variable Explorer or hit Ctrl-Alt-V and you’ll get a box like this one. \u00a0It shows a list of all the variables created by your script. \u00a0<\/p>\n

Bingo! \u00a0There’s mm. \u00a0Expand it and you’ll see all the lines where it is set\/created. \u00a0 In this case it’s created on line 40 by the Min command. \u00a0<\/p>\n

In a long script it’s easy not to see the obvious. \u00a0The Variable Explorer makes it easier.<\/p>\n

Of course, it would also be sensible to use a better naming convention for the variable to avoid such confusion. \u00a0Or use VAREXPLICIT or he could have used {“mm”} to specify the literal string value. \u00a0 But don’t forget the Variable Explorer as it can save a lot of hunting around.<\/p>\n","protected":false},"excerpt":{"rendered":"
