CONTENTS OF VOLUME #19
1. It is always nice to give others a program or two but the
better reward is to have those people return your programs bigger
and better. That is the case in this volume. I had written a
tutorial Pascal tree and donated it to the group. Ray Penley
returned it with Tree4 and we saw great improvements. Now we have
a near final version, Tree5 by Rex Buddenberg. It maintains a
sorted list in a binary tree. It is always possible to improve a
program and I certain hope we continue this trend with this
program. But it now has disk storage, deletion and relinking
ability. Rex has done a good job.
TREE5.COM/PAS/DOC The main program
DISC.PAS Procedures for reading and writing the
leaves to disc file.
ORDER.PAS Procedures for traversing the tree.
DELETE.PAS Procedures for removing a record and
relinking what is left.
MENU.PAS Utility routines.
DATA.DAT
Rex has also done some converting. The following program was
converted from basic. It prints a string of seven letters in
large format- 10 X 7 of normal characters. He explains some of
his trials and errors which all contribute to a interesting
effort. It should give you some good ideas for things to do
yourself.
SIGNS.COM/DOC/PAS
FONT.DAT This is how Rex filled the font.
2. Iron-Fingers Penley has been at it again. This program
called RUNOFF is a text formatting program patterned somewhat
after the Runoff for the DEC PDP-11. The commands available are a
subset of those available in the original PDP-11 version also the
command formats and actions are the same as the PDP-11 version.
However, there some new commands so look it over.
RUNOFF.COM/DOC/PAS/SUB
Ray had sent the following programs several weeks ago but I
couldn't fit them in until now. So this disk will be almost all
of Ray's donations. In answer to some user letters and his own
curosity ,the following programs were created to answer a need.
PASDIR.COM/PAS Allows user program to call directory.
REMOVECC.COM/PAS Will remove or change control characters
also find Hi-bit or strip Hi-bit.
TRIMCOLS.COM/PAS Trims right column or trailing blanks.
SUPERSUB.COM/ASM Public domain up-date of Submit, it is
enhanced and is to be used with XSUB
XSUB.COM/PAS Execute external programs via a Submit
program generated with the user program.
PAUSE.COM/SRC Short routine to print a message to
the console, wait for any keypressed
then return immediately to program.
