!Hmmmm... I seem to remember such a similar query just a month ago...

!As far as I know, there is no standard way of doing so.   There is
!still some hope, because many implementations of pascal will have
!ways to access the command line.
!
!Here are some implementations that I know of that allow access to the
!command line parameters:
!
!(VM/CMS)
!PASCAL/VS	If I recall, R0 is used to point to the unparsed command
!		line string.   You had to write some assembly code to
!		be able to gain access to it.   There was also a
!		way to gain access to the parsed arguments (though they
!		were limited to 8 characters).
!

If I am right, PARMS is a function with no argument in VSPASCAL 
that will return command line arguments in the form of a string.
If you want to know more, I can look up the detail for you.
