-- How to build pForth ------------------------------------

See pForth reference manual at:

  http://www.softsynth.com/pforth/pf_ref.php
  
-- How to run pForth ------------------------------------

Once you have compiled and built the dictionary, just enter:
     pforth

To compile source code files use:    INCLUDE filename

To create a custom dictionary enter in pForth:
    c" newfilename.dic" SAVE-FORTH
The name must end in ".dic".

To run PForth with the new dictionary enter in the shell:
    pforth -dnewfilename.dic

To run PForth and automatically include a forth file:
    pforth myprogram.fth

-- How to Test PForth ------------------------------------

You can test the Forth without loading a dictionary
which might be necessary if the dictionary can't be built.

Enter:   pforth -i
In pForth, enter:    3 4 + .
In pForth, enter:    loadsys
In pForth, enter:    10  0  do i . loop

PForth comes with a small test suite.  To test the Core words,
you can use the coretest developed by John Hayes.

Enter:  pforth
Enter:  include tester.fth
Enter:  include coretest.fth

To run the other tests, enter:

    pforth t_corex.fth
    pforth t_strings.fth
    pforth t_locals.fth
    pforth t_alloc.fth
    
They will report the number of tests that pass or fail.
