FOX2TRH.PRG converts the FOXHELP on-line reference
to Tom Rettig's HELP format, so you can read it no
matter which editor you use to write FoxPro programs.
************************** DESCRIPTION *****************************
Tom Rettig's HELP works with your editor or word-processor, at the
command prompt in interpreters, and even over data-entry screens in
compiled applications. Touch a key and a window instantly pops up
with everything you want to know about any software command,
function, operator, keyword, or symbol.
Three components make up the TRHELP system: "Data Files" contain
compressed information about a programming language or software.
You use the "Reader" to quickly access Data Files no matter what
software you are using. The "Data File Maker" lets you create your
own Data Files or modify existing ones.
Intuitive menus make everyone an instant expert, and speedy hot-keys
let the power-user bypass all menus. The Reader never gets in your
way: it works the way you think instead of making you think about
how it works.
Powerful five-way search lets you find any entry by its name,
functional category, grammatical type, see-also pointer, or detail
text fragment. Functional and grammatical groupings let you view at
a glance all language features belonging to a group, and quickly
select the one right for your immediate needs.
Four versatile output options let you write syntax structures and
valuable source code examples directly into your editor while you're
programming. Or leave a temporary image on your screen and
return to using your editor. Or make a hard copy on any printer.
This pop-up Reader, TRHFOX.EXE, is "tied" specifically to the Data
File produced by FOX2TRH from FOXHELP. It is a completely full
implementation of our commercial Reader, TRHELP.EXE, except that
it reads ONLY this FOXHELP Data File and we give it away as
"freeware." Our commercial Reader reads all Data Files including
FOXHELP plus those that we write and publish for the latest versions
of FoxPro, FoxBASE+, dBASE IV, dBASE III PLUS, Clipper, Quicksilver,
and dBXL.
We also publish a Data File Maker that allows you to make your own
TRHELP Data Files and modify existing ones. The Data File Maker is
available from your software dealer or directly from Tom Rettig
Associates.
************************* INSTALLATION *****************************
The complete TRHELP system is contained in one file, TRH4FOX.EXE.
It is a self-decompressing file that contains this FOX2TRH.DOC plus
three TRHELP files.
Make the directory in which you keep FoxPro the active default
directory. Insert the TRHELP diskette in drive A:, and type
A:TRH4FOX at the DOS prompt. For example:
C:\FOXPRO> a:trh4fox
The three TRHELP files require 160K of disk space when decompressed.
- TRHFOX.EXE is the pop-up Reader file that reads the
FOXHELP.TRH Data File.
- FOX2TRH.PRG is the FoxPro program that makes the Data File
from FoxPro's FOXHELP.DBF.
- FOX2TRH.EXE is called by FOX2TRH.PRG for the final low-level
compile of the FOXHELP Data File.
***************************** USAGE ********************************
Before you can use the TRHFOX Reader, you must create the FOXHELP
Data File that the Reader uses by DOing FOX2TRH.PRG from within
FoxPro. This program handles long strings and requires that
your CONFIG.FP file set MVARSIZ to 45 or more. If your CONFIG.FP
file does not set MVARSIZ, add this line before you start FoxPro:
MVARSIZ = 45
After adding this line, start FoxPro and DO FOX2TRH from the command
window. You only need run this program once, or anytime the FOXHELP
database or memo file changes.
Note that FOX2TRH.PRG requires available disk space about 2.2 times
the size of FOXHELP.FPT for temporary and final output files. The
resulting FOXHELP.TRH file will be about 10% bigger than FOXHELP.FPT
because we add a great deal of information. For example, if
FOXHELP.FPT is 500,000 bytes, you need about 1,100,000 bytes free,
half of which is used to store the output FOXHELP.TRH Data File, and
half of which is used for temporary working space and then released.
You can set a DOS environmental variable "TMP" to use another drive
for temporary files. For example, to put all temporary files in the
root directory on drive D:, type this at the DOS prompt before
entering FoxPro:
SET TMP=D:\
Once the FOXHELP.TRH Data File is made, it and TRHFOX.EXE are the
only two files you need in order to use Tom Rettig's HELP. Before
you blow away FOX2TRH.PRG though, you might want to take a look
through it because it demonstrates many new FoxPro features
including low-level file handling and long strings that you can
use in your FoxPro applications.
To start the Reader, type TRHFOX at the DOS prompt before starting
FoxPro or your editor. If you use no options, TRHFOX will be memory
resident.
All documentation, including what you are reading now, is available
from the Reader's Help menu. Once activated, press F1 and read the
entries on the Help menu. The Reader does quite a lot, and you will
find everything fully described in the Help entries. For example,
the entry called "Start" has complete information on starting up,
optional parameters, and memory usage.

Title : Tom Rettig's HELP conversion for FoxPro
Keywords: HELP TRHELP FOXPRO POPUP REFERENCE DOCUMENTATION
TRHELP is pop-up quick reference software that lets you look up
reference information while you are programming in any editor
like Brief, Q-Edit, etc. This utility program converts the
FoxPro FOXHELP file to TRHELP format, so you can reference it
outside of FoxPro. Includes the TRHELP Reader for reading the
converted file. Self-extracting, just run. Version 1.02,
December, 1989.
The contents of FOXHELP.DBF and FOXHELP.FPT are the exclusive
property of Fox Software, and are subject to the terms of the
license agreement under which they are acquired. Changing the
format does not change the license and you must treat converted
files the same as the originals. Consult your FoxPro license to
determine your rights thereunder.
