You want to test whether a line containsVar1 = FalseANDVar2 = True? Or whether a file containsVar1 = FalseANDVar2 = True? Or something else? An example would help.

What you really want is "OR", not "AND". If "AND" is used, then logically, you'll get no lines (unless the line is something like "MyVariable = False...MyVariable = True".
Use "extended grep" and the OR operator (|).
grep -E 'MyVariable = False|MyVariable = True' FormA.frm

Yes, you're right. I wanted OR but incorrectly specified AND. Thanks.

Incidentally, I noticed this works only with an uppercase "E" and not a lowercase "e". So grep arguments are case sensitive I suppose.

It also works withegrep(which I use) instead ofgrep -Ewhich is the more canonical.

You should use
grep "MyVariable = (False|True)" FormA.frm
where the | sequence mean an alternative, and the delimiters ( and ) are for grouping.
