I recently wanted to abreviate something like

Code:

;This is a simplified example
 Lab0:
 Lab1:
 Lab2:
 Lab3:
 Lab4:
 Lab5:
 Lab6:
 Lab7:
 Lab8:
 Lab9:

into

Code:

repeat        10
 Tmp= %-1 + "0"
 Lab#Tmp:
end repeat

but unfortunately the second variant doesn't work.
Has anyone an idea how to do this?

What you actually want to achieve? (you can't simply define such labels arrays)

I actually have to repeat a piece of code, but the code is slightly different in each repeat; so I use the % a lot. Furthermore, I must define labels like those stated above.

You can't, because all the labels are defined during preprocessing while the repeat directive is executed during assembling when all labels are already defined.

Try using @@: label with @f and @b references instead. (edit: No, you can't inside "repeat" because of the same reason...) Also, you can try to create the loop in the preprocessing stage, where you still can define labels: some macro with needed count of arguments and your code defined in "forward" section - inside the macroses you can use local labels as well.

Regards.

This is as far as I knew it too. Isn't there another solution except using those difficult to maintain @f and @@ stuff?

Is this a solution ?
...

Code:

rept 10 mylabel {
     label L#mylabel                 ; create L1 bis L10
         nop
         nop
 }
              
    display_decimal L1      ;4202496
            display 13,10
       display_decimal L2      ;4202498
            display 13,10                           
    display_decimal L3      ;4202500
            display 13,10
       display_decimal L4      ;4202502
            display 13,10
               nop
         nop
         nop
         nop
         nop
 ;----------And....when you need one of them
 ;----------use it after redefinition with equ
       ;----------because they ar label.
   foo:
    L4 equ foo
  display_decimal L4      ;4202521
    ret

This is a very old thread - the REPT directive was not available at the time (it was introduced in version 1.62, 16 June 2005).
