Important Notice
The pages on this site contain documentation for very old MS-DOS software,
purely for historical purposes.
If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.
QuickBASIC Invalid File Name
Make sure the file name you entered in the dialog box
conforms to these rules and assumptions used by QuickBASIC:
■ A file name has two parts: the "base name", which is
everything up to but not including the period (.), and
the "extension," which includes the period and up to
three characters. You can use any combination of upper-
and lower-case characters; these example filenames all
refer to the same file:
abcde.bas, ABCDE.BAS, and aBcDe.BaS
■ If the file name is 8 or less characters with no
period, QuickBASIC assumes the extension .BAS. If the
file name is between 9 and 11 characters, QuickBASIC
puts a period after the eighth character.
