Description:Checksummer for BASIC listings
Developer/Porter:Stefan Haubenthal
Short: Checksummer for BASIC listings
Author: felix@palmen-it.de (Felix Palmen)
Uploader: polluks+aminet sdf lonestar org (Stefan Haubenthal)
Type: dev/cross
Architecture: ppc-morphos; m68k-amigaos

Build requirements:

- gcc or clang (for `mksums` and converting a checksummer to BASIC)
- ca65 / ld65 (for building the individual checksummers)
- petcat (for creating .PRG files from BASIC sources)

Build instructions:

To build everything:


make is expected to be GNU make, so e.g. on a BSD system, type `gmake` instead
of `make` everywhere.

To build only the `mksums` tool:

make mksums

To clean up:

make clean

To clean up AND remove the targets:

make distclean

make variables:

CC command to execute the C compiler (default: cc)
CFLAGS flags for the C compiler (default: -g0 -O2)
C64AS command to execute ca65 (default: ca65)
C64LD command to execute ld65 (default: ld65)
PETCAT command to execute petcat (default: petcat)


For creating checksums:

mksums [-s] < input.prg > checksums.txt

creates checksums for the input.prg BASIC program in checksums.txt
-s: allow shifted spaces in input.prg

For typing a BASIC program with checksumming:

- Load the .prg for your target platform
- Type `RUN` and `NEW`
- Start typing your program, checksums appear in upper right corner
- When finished, SAVE your program to disk (never use the datasette!!)
- Reset or turn of computer to deactivate the checksummer
- Load your typed program and enjoy.
