Pete's QBASIC Site

hii every body i'm working in updating project was developed in qbasic scince 1988 ,i face many problems understanding the code statments such as:

dh=cid-rod : dh2=cid*cid-rod*rod

y(1)=pvd:y(2)=od
IF ABS(y(1)-pvd)>10 GOTO 100

other mater is how to make the program prints the output to a usb printer attached in a network or directly to my computer ?
and how to make the output saved to excell sheet ,if possible?

thanks alot for your worthly help

Just two assignment statements that could be in separate lines. In QB you can put several statements in the same line by separing them bycolons (:)

Two assignments to the co,ponents 1 and 2 of the array y. There must be a DIM y(size) as type at the start of the program to declara the array

ABS is th absolute value of the expression if it's bigger than 10 the program jumps to a line labeled with a 100

You must make the printer available to DOS in the Windows printer settings (It was possible in W98 and W2000, don't know in XP). You assign the printer to a false LPT1 port. Then you can use QBasic's LPRINT.
If this does not work you can print to a file then print with Notepad (It will garble the line drawing characters)

To export to Excel write to file using WRITE #. The resulting file is a csv file, easily imported in Excel

BTW: Moro145 sounds strange to spanish ears, as moro is here a derogative. But well, if you like it...

Just a note regarding line drawing characters.
In WORD 2003 of Windws XP, you can see line drawing characters by doing the following:
1) Print to a file with a different file extension, like .FIL
2) Get into WORD.
3) Word presents a small window called "File Conversion". In this window, select "OEM United States" from the menu.
4) Word will now show your text with the proper line drawing characters.
5) You can now print this Word file.

The above post was mine (Moneo).

I just remembered that the above also worked for me with Word under Windows 2000.

Sorry, but that response has nothing to do with this thread.
