Makes a nifty display.

I'll add this to the main program later on I'm still working on other routines as well.

I've uploaded a new version of the "Inline" program. I've done away with all the POKEs for parameter passing. Without the POKEs the GOSUBs are no longer needed so things are bit faster as well. Parameter passing is now in the form... 10 PRINT USR FILL;[Lines],[CODE CHR "X"] I've added two new routin...

I'm tending to forgo using LPRINT for parameter passing as it would make the programs incompatible with ZXPand.

using 21 LPRINT C$(1 to 2); is easier. Then the machine code can fetch PRINTABLE(!) characters from printer buffer (address 16444....) and the length of the basic code does not need to be calculated to call the machine code (line 20). A single number X can be passed to m/c using RAND X and fetch th...

I'll add a smaller demo to the main program later on.

If you can think of any other, not too complicated, routines let me know. I'm thinking a one line text scroll might be useful, for instructions etc.

Various BASIC extensions, like scroll down, converted to "Inline" formats.

See the enclosed Readme for more info.

Updated the program, 08/30/23. Modified the Quick Print routine slightly.

Standard and Chroma versions although both work in either format.

PLOT and UNPLOT work as expected except the plot coordinates are 64x48 instead of 256x192.

PS actually the PLOT coords are 64x44 but can be increased to 48 easily with MC.

The RND function returns an integer value between 0 and 32768 so to have a range between 0 and 5 divide the results by 6554, 0 to 10 divide by 3277, 0 to 20 divide by 1638.

Range of 5 to 25: 5+RND/1638
