Or ACTION=STRACE - you won't want to look at the data from the action itself, but this will let a DISPLAY SLIP,ID=xxx show you what you want, if you don't mind learning only about the number of times that can be represented in a SLIP matchlim value (the limit is 65535). The display will show the number of matches so far (until the trap gets disabled for reaching the limit)
In the general case, there is no tool you could use, whether free or not, that would provide that information. The general case is where a program learns of the address to use by using CSVQUERY and just branches there. The specific case of using LINK/LOAD/ATTACH/XCTL to route control to the module could be determined by such tools.
