"MLC's first command with an argument, that is at least moderately complicated has been added: STOP! No, it doesn't stop the program or something like I first thought when I was programming in MLC for the TI-86. It stands for STOre Picture. This command stores the current contents of the screen in a buffer that you get to name. w00t, so that means you can do something like this:
#STOP mybuffer
Note that the name can only be up tp 8 characters. This command also doesn't use a complex string parser or anything - it just uses the all of the characters up to a newline or whitespace character, and the maximum is 8. The maximum amount of pictures that one can have is 5, but I can increase that (or decrease that) if you all feel that more (or less) are needed. I'm probably going to increase that amount.
This can be compared to: StorePic 1 in TI-BASIC on the TI-83+, or StoPic mybuffer in TI-BASIC on 68K calculators. The MLC version is better though because it's faster, supports grayscale pictures, and the names don't have to be numbers (on 68K calculators, the names don't have to be numbers either, but...).
"
"I added RCLP, which is like RecallPic in TI-BASIC for the TI-83+ (I think it's RecallPic, isn't it?). RCLP didn't take much work because I basically copied the code from STOP and slightly modified it.
I'm going to try to get a screenshot up of a demo MLC program. It's going to use a command called AAAA which really isn't an MLC command, but it'll be there just for the demo. It just writes some zeros and stuff on the screen. When I finish the TEXT command though, it won't be needed."
There are also four other commands that the interpreter recognizes: CLRS (CLeaR Screen), PAUS (PAUSe), DRAW, and HALT. Here is an explanation of them:
"
CLRS. It clears the screen.
PAUS and DRAW. Commands may also begin with "#" (for compatibility with other versions of MLC) or "|" (for easy access on 68K calculators, but no compatibility. Maybe in the converter, I could make it convert "|" into "#"). PAUS obviously pauses the program, waiting for any key press, not just enter. DRAW updates the screen, because all drawing commands are drawn to hidden buffers. This makes MLC programs automatically double-buffered.
HALT. It stops execution of the program.
"
What awesome progress, keep up the good work!! :king:
Edit: forgot to post the screenshot:

Thanks for posting this, tifreak8x, and thanks for all of the support. :)
I could make it #STRP, but that would make it not compatible with other versions of MLC. I could make it support both, which would make it slightly slower and larger, or I could just make the MLC converter do a little more work when converting. I'll set up a pole (probably not today though because I really have to get going soon).
I also might include an option that lets MLC programs not have to use #DRAW all of the time to update the screen. It can become a bit (only a bit ;)
) tedious if double-buffering is unneeded but #DRAW still has to be used. Post by: Liazon on November 06, 2006, 04:56:00 pm

Remember that this would also make older MLC programs not compatible.

And you are very welcome bfr. :)
I figured since dragon__lance retired, and xlibman isn't around, it fell to me to start makin the news post... >.<
