Slow ZX-jen progress

Another short program, demonstrating progress in the handling of variables. You can now assign integer variables with let, and assign them a number (other operations will be implemented in the future) and print them, either with ; (means no newline will print) or without. The output contains the usual debug statements, l for 'let' and p for 'print'. As you can see there is still a slight bug in the print command where it doesn't check the length of the read sentence, and thereby it assumes that line 40 ends with a ;. It used to, in the past, but it was erased. Unfortunately, this was not yet realised by the program. This will need to be fixed. But lots of things need to be fixed still. At least it seems like it is doing something.

I decreased the size of the image here. If you want to see a blown up version of the screen shot, look at the previous post. It will show approximately how the screen is built. Also, thank you for the comment on that post... I always enjoy comments.
