The Atari Assembler Editor bug list:

bug:

Description:

- impossible to supply an inline comment for a line which only has a label. For instance:

280 OSRC ;OPEN SCREEN ROUTINE

This will generate an error six.

Solution:

280 OSRC NOP ;OPEN SCREEN ROUTINE

else

280 OSRC .OPT LIST ;OPEN SCREEN ROUTINE

bugs: Thanks to Rybags from AtariAge:

Description:

- some error situations in Debug will send you back to Edit mode without your requesting it.

- commands in Debug which also match a 6502 mnemonic won't work, you need to put a space in between command and parameter, e. g. LDA10 or DEC won't work but L DA10 and D EC will.

- extremely annoyingly, you must use BRK to return to the debugger.  A program using RTS will usually hang or crash.

- if your program disables stage 2 Vblank the Break key won't work.  Probably because the Rev. A OS didn't have a Break key vector, it was added later.  So the Assembler Editor cartridge had to use a workaround which has deficiencies.

- zero page labels will generate a 2-byte address when used with instructions that also have absolute mode, e. g. LDA RTCLOCK+2 where RTCLOCK = $12
