Mecrisp Stellaris Forth Dictionary 0

5 minute read

Where I keep my dictionary 0 with all of the basic Forth definitions.

Introduction

It helps to have the complete dictionary for Mecrisp-Stellaris Forth, this is dictionary 0 which has my most basic definitions. I load this before I start doing any work in Forth on the RP2040.

\ main dictionary for words which have been debugged
compiletoflash
: words4 ( -- ) cr  \ A columnar Word list printer. Width = 20 characters, handles overlength Words neatly 
   0				    \ column counter
   dictionarystart
      begin
	 dup 6 + dup
	 ctype			    \ dup before 6 is for dictionarynext input
	 count nip		    \ get number of characters in the word and drop the address of the word
	     20 swap - dup 0 > if   \ if Word is less than 20 chars
		   spaces swap	    \ pad with spaces to equal 20 chars
		   else drop cr	    \ issue immediate carriage return and drop negative number
		   nip -1	    \ and reset to column -1
		   then		       
		      dup 3 = if 3 - cr \ if at 4th column, zero column counter			   
		      else 1 +
		      then
	 swap		       
	 dictionarynext		    \ 	( a-addr - - a-addr flag )
