Adder QL Macro Assembler

Adder's Assembler development package was released to complement the QL Advanced User Guide.

The Assembler includes an integrated editor/assembler (similar to Assembler Workbench, so you do not have to save the created assembly listing to microdrive/disk and then assemble it separately from the file.

The program also allows you to change registers and memory locations on the fly, for debugging the completed program.

The advertised features included:

Full 68000 macro assembler
Integrated full screen editor
Conditional assembly
External library file inclusion
Complete error checking diagnostics
Comprehensive manual

It appears to only work in 128K unfortunately.

Pressing H from within the assembly brings up a short help file explaining the various commands available, which include the ability to list a file with hexcodes, lock or unlock the Symbol table, and dump an area of memory
