Cut binary file

If I want to shorten a binary file, how can I do that?

When i use LOF(X) QB says the file has n length. Is it possible to trick QB so LOF(X) says n-1 length, or do I have to make a new shorter copy of the file?

Interesting, I thought QB was 100% safe regarding variables, that it generated some kind of oveflow error when the numbers were out of limit. Newertheless it's no problem if one knows about it. Thanks!

Why not the same result?

I?m confused about these few lines. Does anyone know why the number 20070501 becomes 20070500 in the last kolumn? CLS number$ = "20070501" PRINT number$; day$ = LEFT$(number$, 8) PRINT USING " ########"; VAL(day$); day = VAL(LEFT$(number$, 8)) PRINT USING " ########"; day The output is: 20070501 200...

the biggest i could get to work was 125,125....so i made mine about 120,80...when i tried 900,900(a map) it locked up... Seems like max is 180,180 with integer (2 byte) and 127,127 with long or single (4 byte), a 64k limit. So 300,300 integer it should be 300*300*2=180 kb. After rewiewing my code I...

Made a quick test, seems it will take to much time, I?ll take a look at VB for Win to se if I can solve it there instead. Thanks anyway. :)

Large arrays

Does anyone know how to use arrays bigger than (180,180) in Qbasic or Quickbasic? Is it possible to use arrays of size (300,300) wich is 90Kb, or even better, (300,300,300) wich is 27 Mb? It seems one must use dynamic arrays, some switches in the command line, and some sort of EMS but I dont underst...
