Save some bytes in breakpoint handling routines

[ddt180.git] / ddt180.z80

; Disassembled ddtz.com, version "DDT/Z    [8101]"\r
; with modified relocater.\r
;\r
; Build steps:\r
;   - Assemble to a .REL file with M80 or a compatible assembler.\r
;   - Use Digital Research Link-80 to generate a .PRL file (op switch).\r
;   - Cut the .PRL header (first 256 byte) end rename the result to DDTZ.COM.\r
