Hi gang! Life is finally settling back down for me so I can start playing with my mini compiler. I'm trying to pickup the pieces from where I left off and our...

... The generalisation is a 'procedure call' node, with "print" being the name of the procedure, which is one of the parameters. You may or may not want to...
The way I worked this was to have the print statement create a procedure node as Graham suggested. Each proc node has the option to be an implicit or explicit...
Thanks for all the input Tim, Graham, and Rainer. I am still using a very simplistic example code file for my parser/lexer to get a good base and will expand...

Before we get into too much detail, tell us how you want your language to behave from the user's point of view. What do you consider an error? Syntactically,...
I will try to answer your questions as best as I can. The language is expected to follow a very similar premise as ANSI BASIC does. The language will have...

I take it being a commercial thing we don't get to see any code? I'd be interested to see the byte code interpreter, or maybe some discussion of it. Do you do...
Hey Tim, good to see you pop up again. How did the finals go? Done any work on your compiler since we heard from you last? (done very little myself, but...

The compiler would permit "123" + "456" to be concatenated as "123456" but when the multiplication node is examined, it would throw a type mismatch exception...
