V5.05.04RC14

http://geoffg.net/Downloads/Maximite/CMM2_Beta.zip

Significant performance enhancements (c 10%)
More special case code for the EXECUTE command when "executing" the RUN command: It now will interpret the search path and will not tokenise text after the filename literal

Wonderful Peter, I've tested the tokenisation update to EXECUTE and it works.

Thank you,

Tom

Incredible performance gain!

From 8.44 FPS to 9.45 FPS on Wolf 3D in a medium demand area (to gain one more single frame per second is a hard task in this game).

And OPTION RAM no more gives a syntax error.

Thanks a lot!

Ok, not sure if this is the new spot to report errors...

I'm still on RC 4 but given nobody has reported this I suspect it's still a bug...

if you try to do the following:

sprite read (myvar+1), x,y,width,height,pagenum

it will give the following error:

Error: READ is not declared

Seem like it's not possible to calculate the sprite number in the read command.

I'm wondering if that's why I'm also having problems then trying to do sprite show (myvar+1) and getting back an Error: Buffer not in use

Try removing the brackets:

sprite read myvar+1, x,y,width,height,pagenum

MMBasic is looking for an array called read()

A bug for you Peter.

If a variable starts with rem and is the first 'word' on a line, it is treated as a remark.

remainder=4
remi = 6
remo = 8
PRINT remainder
PRINT remi
PRINT remo

DIM remain=4
f=0 : remi = 6
IF x = x THEN remo = 8
PRINT remain
PRINT remi
PRINT remo

0
0
0
4
6
8
>

The work-around is to rename the variable.

aha! that would explain why one of the programs i wrote would never work. it was for calculating the remaining space left in a removal truck, and email you a reminder when space was getting low

cheers,
rob :-)
