Is it possible to perform a numerical comparison of two values from within procmail?

Equality, greater than, or less than?

I can test if a variable has been set, and assume it's a number... but if it's set to some junk/garbage I want to apply a default numerical value to it.

'man procmailsc'.

Procmail can perform some basic math via use of the scoring functionality, though that's not what scoring was intended for, so it's a bit obtuse. For more involved math, you can always use 'bc' and assign the results to a variable inside procmail (though this would be processor costly if done frequently).

Perhaps you could give a concise example of what you're trying to accomplish?
