How do I make a custom dotted line? by qbasicking
Posted: 15 Sep 02 (Edited 1 Sep 03)

Most people know how to make a broken line using &H5555 and &H2222, but say you want a line that is an oddball and you don't know the code for it.  Do you have to use trial and error, not any more.

The last number is figured out in binary, and it goes in loops of 15; here is a chart that will help you

16384 8192 4096 2048 1024 512 256 128 64 32 16 8 4 2 1

so say you want a line that goes 0,1,1,0,1,0,0,1,1,0,0,1,0,1,1

figure out it out by plugging it into the table and adding all the values together

16384 8192 4096 2048 1024 512 256 128 64 32 16 8 4 2 1
     0      1       1    0       1      0    0     1   1    0  0  1 0 1 1

Now add up all the numbers that had a 1 under them

LINE (100,100)-(200,100),,,13515

Here is a FUNCTION to help you in your programming, so now you can use

a$ = "011010011001011"
LINE (100,100)-(200,100),,,Bin2Dec%(a$)

FUNCTION Bin2Dec% (number$)
place = 65535 / 2
FOR a% = 1 TO 16
    c$ = MID$(number$, a%, 1)
    IF c$ = "1" THEN num% = num% + place
    place = place / 2
Bin2Dec% = num%
