; This program opens and utilizes the requester.library in order to use
; the new SPECIAL_REQ flag. This flag allows us to display a list of
; strings in a requester with all the features of the FileIO requester.
; Because version 0 of the library did not support this feature, but version
; 1.4 now does, we must open the library with version #1. Old applications
; that do not know about SPECIAL_REQ will still work with this version of
; the library. It is backward compatible as far as the disk IO features are
; concerned.
; If running this program from the CLI and you specify any argument on the
; command (i.e. 1> TestFileIO blort ), then the window will open on a hires
; screen. You can then see what the requester looks like in hires.
; For Manx, ln -o TestFileIO ManxStartUp.o main.o cl32.lib
;
; For Others, Blink StartUp.o main.o amiga.lib NODEBUG to TestFileIO
