[Info-vax] OpenVMS - DCL - Data entry filtering

[JF Mezei]

In ALL-IN-1, there was a very neat function called

		make_file_name("string")


Basically, you gave it some string and it ensured it was within syntrax
of the file system. If no string supplied it generated those wonderful
random letter ZWYUEYDNDS.WPL file names.

It makes for much cleaner code rather than having to roll your own
string scanning and character replacement routines to create file names.

For a DCL variant,  specifying the device name could verify file system
type and create the file name according to that file system's
capabilities. (otherwise, assume ODS-5)
