Hi I'm new to pbforth and after trying it out I'm not sure what state it is in. I'm baseing what I do on the guide in extreme mindstorms. After some research I find a number of words no longer exist. Is there a way to produce a library check word (...) (21 years ago, 19-Aug-03, to lugnet.robotics.rcx.pbforth)

If you;ve got the most recent versions of pbForth, and you have Active Tcl installed, then click on the rcxtk.tcl file and the pbForth console should be launched immediately. At that point, you can upload the pbForth.srec file using the (...) (22 years ago, 3-Sep-02, to lugnet.robotics.rcx.pbforth)

Richard, A little known fact is that if you "punctuate" a number with any of the following characters ,./-: you will get a double on the stack in the old FIG Forth. so 123-4567 will put the double value 1234567 on the stack. So why doesn't 0= get (...) (22 years ago, 23-Jul-02, to lugnet.robotics.rcx.pbforth)

Hi, While entering a program last night, I typed =0 instead of 0=, and the interpreter accepted it; it took me quite a while to work out why my program wasn't working properly. =0 does not seem to be a word (ie ' =0 results in the "not found" error) (...)

(...) Hi, the nice thing in this solution is that it doesn't inspect or touch the user return stack at all. The structures that are used to get to the FIP (instruction pointer) - namely: the position of the saved D-stack in the *private* R-stack and (...)

Hi, (...) Yup, that does what I want, although I can't remember enough about forth internals to work out why it works. But it does seem to depend on the return stack having a particular structure, so I do wonder - what happens if the interrupt (...) (22 years ago, 20-Jul-02, to lugnet.robotics.rcx.pbforth)
