( press PgDn to move to the next screen ) press PgDn to move to the next screen press Esc to get out of the editor type ED to return to the editor ( end each command or line by pressing the Enter key ) get out of the editor & type .FILES for a list of currently open files. to get back into the editor at another screen, type n EDIT e.g. 300 EDIT to open an additional file, type .FILES to see what screen numbers are already in use & pick a larger number and type n OPEN <file-name> e.g. 3300 OPEN SUPPL.SCR to create a new file, type NEW-FILE <file-name> if the word NEW-FILE is not in the dictionary you will have to load it first from the file SUPPL.SCR. Browse thru that file to find the screen number & type n LOAD to save additions to the dictionary type SAVE <file-name> e.g. SAVE PYGMY2.COM to change the default files that are opened automatically, see screen 77 in PGYMY.SCR note that files are not restricted to the current subdirectory, you can specify a full drive & path name with OPEN. If you are using PYGMY to learn Forth using the book *Starting Forth* by Leo Brodie, browse thru the file STARTING.FTH for tips on making the examples work. Pygmy includes an 8088/86 assembler. See the file ASM.DOC for more information. Pygmy can recompile itself. It is easy to customize it by editing its source code and recompiling it. For example, you might want to change the maximum number of files that are allowed to be open at one time, or you may prefer one version of FORGET over another, etc. See the file META.DOC. VOCABULARIES PYGMY, like cmFORTH, has two vocabularies: FORTH & COMPILER. Compiler words are immediate by virtue of being in the COMPILER vocabulary. When in INTERPRET, words are only looked up in FORTH. When compiling, words found in COMPILER are executed immediately otherwise if found in FORTH they are compiled into the new word. To force compilation of a COMPILER word, precede it with a backslash ( \ ). This is used in place of the FORTH-83 word [COMPILE]. CONTEXT holds the number that represents which of the two vocabu- laries is current. Whichever it is, that is the vocabulary into which new words will be linked. FORTH & COMPILER set CONTEXT to the appropriate number. For additional information, browse through all the files using the editor ( n EDIT ) and the PgDn & PgUp keys.
