trouble with counter

[Kevin]

what i need it 2 do and ,maybe a counter is the wrong way 2 go is every lets say 12th time this function is called go2 another function instead rep doesn't work it just repeats the function over and and over.these functions are not part of the main macro.they are called after the macro ends using atend
ex


main macro
statements...
....

.....
atend function 1
then after function 1 finishes it calls function 2 when function 2 finishes it calls function 3
but every 12 th time i want 2 call function 5 instead of function3.these function do not repeat there are onlt called after the main macro ends?
