This code don`t work
Code:
push aS
aS: '%s', 0
    

But if rename aS to aS_, code compiled.

"as" is a reserved word.

You can use single letter labels.
Code:
push a
a: '%s', 0    
And indeed any length label you want, including very very long names. But you have to avoid the reserved words.

Actually if you had reversed the lines the error message would have been more enlightening.
Code:
as:
push as    
And the result:
Code:
as:
processed: as:
error: reserved word used as symbol.

All reserved words are valid in any mixed case.

as == aS == As == AS.

This is different from normal labels, which are case sensitive.

a != A
