I am 18 (almost 19)
I started using computers and MS-DOS when about 7. I started using QBASIC when about 9, I think. I started using assembly off and on less than a year ago.
Regards,
Michael

There is a simple option: defint a-z red=? green=? blue=? PALETTE 0,red+green*&h100+blue*&h10000 which changes attribute 0 to whatever color you want. red, green, and blue should be values from &h0 to &h3f. Alternately, you could write a font routine than used PUT to draw your text. Using silouettes...

I should have mentioned this earlier. PCOPY is a way of copying the contents of one video memory page to another. In screen mode 0, most people will have 8 video memory pages. So you can use PCOPY 0,1 to save your screen before drawing the menu, and PCOPY 1,0 to restore it after you are done. Also, ...

I need 2 reserved numbers for background/foreground, and then a random amount of variables available for use as ASCII codes. I am not getting what this has to do with PEEK and POKE. You could do something like: DIM foreground AS INTEGER DIM background AS INTEGER DIM ASCII(0 to (80*43)-1) AS STRING ...

### Still not sure exactly what you are asking...

what I need to do is be able to put about 40 sets of 2 numbers in memory... INTEGERs? LONGs? BYTEs? Where in memeory? The video memory? Some QBASIC array? If you mean copying 1 array to another very quickly, you could use a machine code routine to do it faster than interpreted QBASIC. Semi-Graphica...

just in case 16 bit code gets more than 64 KB by segmenting. Each segment is 64KB big. Segments overlap every 16 bytes. (16 bytes=1 paragraph). That meanse you can have segments 0000h to FFFFh and offsets from 0000h to FFFFh. The <b>actual</b> address is the segment * 16 + the offset. (this means 20...

You might put this inside the loop:

IF starttime! > t! THEN
'crossed midnight, timer went to 0
starttime! = starttime! - 86400
END IF

The

seemed to work for me. I don't know why it wouldn't work for you. You can use GOSUB also.

To change directory: CHDIR or SHELL "CD\"+dirname\$ To run a small game: SHELL doscommand\$ To run a large game, here is how I would do it: Use a BAT file to run your QBASIC program. Something like this: @echo off :loop if exist temp.bat del temp.bat c:\dos\qbasic.exe /run myprog.bas if exist temp.bat...

### Yes, it is possible. I've done it.

I know this is several months late, but I haven't been here that long and don't come here very often.

### SYSTEM

P.S.
Also use the SYSTEM statement to end your program, instead of END.

### Shortcut

You want a shortcut (PIF). Do you also want a batch file? Is so, point your shortcut to the BAT file, otherwise, point your shortcut at QBASIC.EXE. Either way, you probably want to use the /run switch. sample batch program: @echo off c:\qbasic\qbasic.exe /run c:\mydir\myprog.bas Or, the command line...
