SHELLCMD()

ok# = SHELLCMD(cmd$, wait#, show#, rv##)



Executes another program. If you want to execute DOS commands, you have to call CMD or COMMAND (on Win9x/ME) and then enter the DOS command. e.g. "CMD /C dir > files.txt"

wait# specifies whether to wait for completion of the other program (TRUE / FALSE)
show# allows you to start the program hidden (TRUE / FALSE).
ok# returns TRUE or FALSE, depending on whether the program could be started or not.

The return value of the other program will be transferred to rv##
