Counting exec arguments?

[paues]

I am writing a program file with an unspecified number of arguments and am trying to figure out how many they are. I call the file using a command such as the one below:

Code: Select all

exec "myNeatFile.prg" arg1 arg2 arg3

and myNeatFile.prg contains inter alia this snippet, which I would believe would count the arguments for me, but simply returns !i=-1:

Code: Select all

!i=0 while @neqna(%{!i},"") !i=!i+1 wend !i=!i-1 @uiprompt("!i="+@str(!i))

Help would be much appreciated.

Is this feature documented? I can't find it in the 7.2 version's documentation
