NOTES FOR USE OF THE WORD LIST
These words are used for programming the TDS2020F and incorporate the latest ANS Forth. There are 509 words in all, contained either in the TDS2020F Forth ROM or in one of two files, #ANS.TDS (ANS Forth words) or #EXTEND.TDS (non-ANS words specific to the TDS2020F). All the words are listed in alphabetical and dictionary orders below, followed by individual definitions.
Word definitions are given in strict ASCII order. In this section, 'ANS' appears alongside all ANS Forth words. Where words are found in the separate files, this is also shown. The stack conditions for each word before and after are shown thus:
stack before - stack after
The top of the stack is on the right. Where the stack effect is different during compilation and run-time, both are given.
When the return stack changes it is indicated like this:
R: n1 n2 - n1 n3
If text is needed following the word in question it is given in single quotes like this:
In this example, from the definition of ['] , there are no stack effects but text consisting of at least one space, then a name, then one space is required after the word, like this: ['] XYZ
