<VALIDFNAME> 

Syntax 

<VALIDFNAME {filename} >

where:

filename              parenthetical string

Description 

<VALIDFNAME> returns 1 (TRUE) if a file called filename could be created
by the user, or already exists, otherwise it returns 0 (FALSE).
<VALIDFNAME> will return 0 if the user lacks SF capability and the named
file does not exist, but it will return 1 if the user lacks SF capability
and the file does exist.

Example 

     &SAVE filename <PROMPT "Please enter file name">
     &BACK badname <NOT <VALIDFNAME <VAR filename>>>

This checks that a user has typed a valid filename in response to a
screen prompt.  If filename is not valid, then the script goes back to
the label badname.
