A few lines about this discussion. It's not true that the code does nothing. It releases a variable that may be declared local or public elsewhere. Also you say it's at the beginning of a main program. But every main program could be a procedure for another main program that you forgot that you used before. So it makes it a lower call. Think of this scenario :
* Anothermain.prg
Cmd_param = doacheck()
do main.prg with Cmd_param
if type("cmd_param") = "U" && Released ?
........
endif

* This type of code also strange could be used in copy protection.
