Atari Assembler Editor - Syntax Error Help

[ColecoFan1981]

Whenever I use the Atari Assembler Editor with Atari 800 WinPlus 4.1, whenever I use the Assembler Editor page, why do I get frequent syntax errors when trying to assemble the code in ASM?

 

EXAMPLE:

10 *=$5000

20 LDA #2

30 .END

ASM'

 

What the above should look like in assembling:

$5000 A9 02

 

Thank you!

With the AsmEd cart as well as Mac-65 you have rules re spacing and placement within a line for comments, directives, machine instructions.

 

Comment at start of line uses ;

For a label you have one space after the line #

For an instruction or directive you have two spaces after the line #

For an instruction after a label you only need one space.

In most assemblers, comments allowed after instructions, usually just one space required.

 

e.g. for all this

 

10  *=$5000
20  LDA #2
30 ; This is a comment on it's own line
40  STA $6000 This is a comment after an instrucition
50  .OPT LIST This is a comment after a directive
60 LABEL1 LDA #3
70 LABEL2 .OPT NOLIST
80  .END
