SCREEN 7 mode available in PB/DOS?

[Paul Panks]

Hey all,

Is SCREEN mode 7 available in PB/DOS? Under QBASIC this puts the screen in a 40 column by 25 row mode
with 16 colors.

Also:

How does one convert text from lowercase to uppercase in GWBASIC? GWBASIC is not blessed with UCASE$ and I am trying to convert an old GWBASIC program for use in QBASIC. Do I convert the text first to lowercase and then use a FOR NEXT-LOOP to convert to upper case? What if the user hits CAPS LOCK and types in uppercase? Do I detect for that? What about words that are MuLtY-cAsEd?

Screen 7 is available on my machine (Dell 566Mhz). I don't know
what video card it has in it tho. Try it on yours see what
happens.

Converting text to upper case "the hard way":

te$ = ""
for x = 1 to len(t$)
h = asc(mid$(t$,x,1))
if h > 96 and h < 123 then h = h - 32 '97 = "a", 122 = "z"
te$ = te$ + chr$(h)
next x

Cheers

It compiles fine and runs fine in the IDE, but screen mode 7 produces a 244 error
when the exact same compiled program is run as an .EXE.

Paul, you have created two topics discussing similar but "very unusual" issues with PB/DOS - as suggested in the other topic, I recommend that you try a reinstall as your problems are "fairly unique"

On a related subject, what is the date stamp on your PB.EXE file? If you have to reinstall, you may as well make sure you are using the latest version of PB/DOS...

Okay Paul, I've run some more tests and here's what I found.
I ran across the 244 error with "Lib All Off". You probably
have that or other-wise turned off your graphics package. Turn
your graphics package back on and try it.

Good point guys... thanks!

(I did not imagine that Paul would have disabled the EGA graphic library from the EXE... )
