Disk File Names
A disk file name identifies a file that contains data or a program. A disk file name
reflects the specified file’s location on a NonStop system. The location of a disk file on
a NonStop system is analogous to the location of a form in a file cabinet. To find the
form, you must know:
•
Which file cabinet it is in
•
Which drawer it is in
•
Which folder it is in
•
Which form it is
Analogously, to find a disk file on a NonStop system, you must know:
•
Which node (system) it is on
•
Which volume it is on
•
Which subvolume it is on
•
Which disk file it is
In general, disk file names:
•
Cannot contain spaces
•
Can contain ASCII characters only
•
Are not case-sensitive; the following names are equivalent:
myfile
MyFile
MYFILE
•
Language functions and system procedures that return file names might return
them in uppercase letters (even if the file name was originally in lowercase letters).
Check the description of the routine that you are using.
