- │ Two More Extremely Useful System Words │
- └──────────────────────────────────────────┘
-
-
- F1 or HELP {name} Get help information on the word {name}.
-
- V or VIEW {name} Look at the source code for the word {name}.
-
- Try: HELP WORDS <enter>
-
- You should find some new ways to scan the Forth word dictionary from the
- information that is displayed. Try some of the suggestions illustrated.
-
- ****** DO IT NOW ******
-
- F-PC is unique in that you get all of the source code for the Forth
- language with the system. If you want to look at the actual source code

-
- Use the ideas presented in the first three parts of lesson 1 to
- construct an original and useful data base. (Not a phone list)
-
- For example:
-
- : C ." 2.997930E8 m/s The speed of light." ;
-
- : N ." 6.02486E26 /(kg mole) Avogadro's number." ;
-
- : E ." 1.60206E-19 C The electronic charge." ;
-
- : h ." 6.62517E-34 J s Planck's constant." ;
-
- There will be a reward for the most useful data base!
- Upload yours here please. We're collecting them!

- │ Instructions on printing out the manual. │
- └─────────────────────────────────────────────┘
-
- During the F-PC installation process the F-PC instruction manual was
- unpacked into the sub directory C:\FPC\HLP . If you haven't already
- done so print out the instruction manual as soon as possible. It
- contains much valuable information about F-PC. You will also find some
- useful *.TXT files in the C:\FPC directory that are used by the HELP
- system. It might be a good idea to print these out for reference too.
