Chapter 6 - Designing Bar Code Labels MERGE "/rom/ERRHAND.PRG" Using the Print Key Instead of using a PRINTFEED statement, we will use a subroutine in ERRHAND.PRG. Because ERRHAND.PRG assigns functions to keys, you can create a loop in the program to get a label every time you press Print: 160 GOSUB 500000 170 GOTO 170 RUN Try pressing different keys on the printer keyboard. Only keys that have been assigned a function in ERRHAND.PRG (Pause, Print, Setup, and Feed) will work. You can break the program by simultaneously pressing the Shift and Pause keys. Save the program again under the same name: SAVE "LABEL1" The previously saved program "LABEL1.PRG" is replaced by the new version. ERRHAND.PRG can easily be modified to fit into more complex programs and Intermec recommends that you include it in your programs until you are skilled enough to create your own routines for error handling.
