Demo of a high level macro.

[hutch--]

This macro was designed for working in higher level code where you mainly use memory operands for loop code comparisons. It always uses RAX for the comparison as this is safe in a context where high level procedures use RAX for their return value. This type of comparison can always be done manually but the macro is aimed at clear coding in a high level context. For those with a sense of humour, the format is not dissimilar to ancient COBOL but it reads OK and is easy enough to use.

  lbl0:
    conout str$(var),lf
    sub var, 1
    jump lbl0 while var gt cnt      ; evaluate from bottom of loop


So that is the equivalent to this one, I suppose?

.Repeat
    conout str$(var),lf
    sub var, 1
.Until var<cnt

Doubt it, ML64 does not support .Repeat or .Until  .
