Code:

lb_cnt EQU 0
macro mlbCount {
      ;if ~ defined lb_cnt
      ;  lb_cnt = 0
      ;end if
   .lb_cnt:
        lb_cnt EQU lb_cnt+1
      } 

In code:
mlbCount 
mlbCount
mlbCount

fasm get error: '.lb_cnt: symbol already defined'

I expected this:
.0:
.1:
.2:

Use REPT to convert numeric value to decimal token that can be used to form the name:

Code:

lb_cnt EQU 0
macro mlbCount {
  rept 1 this:lb_cnt, next:lb_cnt+1 \{

   .\#this:
        lb_cnt EQU next
      \} }
