Repeating and Ending macro

[Two]

Trying to make a macro that keeps repeating itself until I stop it. Did a search on the topic and the closet I got was this post:
start the macro again and again

I've got the part on repeating down (I think), but can't figure out how to stop it (only way is to close the program that is being macroed). Also don't understand what this command is:

str+ stopmac
stopmac="Stop"

At the moment I have the below as a function:
str+ stopmac
rep 1
,int w1=act(win
,rig+ 933 757 w1
,wait 5
,rig- 960 600 w1
,wait 5
,lef 162 260 w1
,wait 5
,lef 210 524 w1
,wait 5
,lef 893 190 w1
,wait 5
,'V
,wait 20
,lef 982 771 w1


Some help would be appreciated, thanks.
