Adding to a variable.

Almost to embarrassed to ask but...

I found some code used in updating progress bars and gauges. Following snippet:

PROGRESS = $PROGRESS$ + 1
PROGRESS1 = $PROGRESS$ * 10

Set Variable FRED to 3

How can I enter a statement like FRED = $FRED$ + 15? The PROGRESS and PROGRESS1 statements are valid but I can't work out how you actually enter those in the MSIcode window.

Any ideas appreciated.

Doh! Mathematics? I was looking at it the other day but it never occurred to me to think of it as useful for adding two numbers together. Thanks for the light bulb Styx. Now, if I can only work out how to switch it on. Homer Simpson would be proud of me and welcome me as one of his own. Doh!

EDIT: I should have realised that by positioning on the statement and hitting the enter key would have displayed the Mathematics dialog.

Also, to append/prepend a value to a variable, you can call Set Variable VAR to "prepend $VAR$ append" etc...
