Code:

macro x { local l1
l1:
}
.22: mov al,2
       x
.33:
 cmp al,3
 jbe .33

fasm get error. Not found .33

I fixed macro x:
macro x { local .l1
.l1:
}
Did this fix right for macro x ?

Second question.
What is good\more stable for fasm Fix or EQU(using in some procs and macro) ?
I want write many(2000) EQU

Works for me.

Try

Code:

macro x { local l1
jmp l1
l1:
}
.22: mov al,2
       x
.33:
 cmp al,3
 jbe .22

Get me error: undefined symbol 'l1?g.22'

This is normal. You are defining a new base label with the macro x.

Try this:

Code:

macro x { local ..l1
jmp ..l1
..l1:
}
.22: mov al,2
       x
.33:
 cmp al,3
 jbe .22

The double dot does not create a new base name for the single dot labels.

Note that the macro is not the cause here.

Code:

.22:
l1: jmp .22 ;error

Compare to:

Code:

.22:
..l1: jmp .22 ;okay
