I'm receiving RS232 with a basic module and am trying to compare the input string to another string. for instance - 10 Input2 ,$(0) 20 If $(0) = "0504 " then whatever.. This isn't working - it seems to ignore the "04 " portion of the data. Question is what do I convert a string to when comparing? Help!

You need to use the INSTR statement to do full string compares.
Change line 20 to
20 IF INSTR($(0), "0504 ") THEN whatever
If the patterrn string ( "0504 ") is found in the search string ($(0)) the IF statement will be true.
