I'm scanning through a text file line by line, and need to determine whether or not the current line is blank or not.  The problem is that these lines have a varying number of blank spaces.  I assume I need to check for an absence of numeric or alphabetic characters...

Try this:

IF LEN( TRIM( Text$ ) ) < 1 THEN (is blank)

You could do something like this:

For x = 1 to Len(FileString)
     If Mid$(FileString, x, 1) <> " " then
          StringIsNotBlank = True
     End-if
next
