- HOW'TO TRY the B editor:
-
- The directory B/ex/try is here to try the B editor interactively. The
- example B workspace here can always be regenerated with:
-
- cd ../generate
- cp \'* ../try
- cd ../try
-
- Now enter the B system from this directory with
-
- ../../bin/b
-
- After the B system has started up it will prompt for a command with
-
- >>> ?
-
- Slowly type `s', then `t', (no capitals needed) and you should see the B
- editor suggest the SELECT and START commands, respectively. Now
- press [TAB] to accept this last suggestion, and [RETURN] to enter the
- START command to the B interpreter. This command will promt you for
- input, with
-
- ?
-
- Just enter about four lines of text, (which will be echoed), ending with an
- empty one (press [RETURN] immediately). A short `poem' should be generated
- by the B interpreter.
-
- If you are already familiar with the B language, you might try to edit the
- START unit by answering
-
- >>> ?
-
- with
-
- :START
-
- For example, try to remove the SET'RANDOM command, to get random
- results on the same input. Or make the unit delay the echoing of the text,
- entered by the user, until after the reading of the empty line. For test-
- ing purposes you should at least try the arrow keys to move the focus
- around.
-
- You can undo any change by pressing [BACKSPACE].
- You can get help with ?.
- You can leave the B editor with control-X.
- You can leave `b' by typing QUIT.
-
- For more information, see the manual pages `B(1)' and `bterminal(5)', and
- the User's Guide.
-
- See the B Newsletter, issue 2, for a description of the `generate' program.
-
- If there are any problems with the editor, consult the `bterminal(5)'
- manual entry before trying anything else.
