Short: Complete ARexx reference. AmigaGuide.
Type: AmigaGuide
Uploader: R.EVANS6
Author: R.EVANS6
DESCRIPTION
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is a complete ARexx reference with tutorials and examples. It includes
argument templates and descriptions of all instruction keywords, of
built-in functions and of the functions in rexxsupport.library. The basic
elements of the language are fully explained.
It is a shareware offering. The suggested fee is $15.
ARCHIVE CONTENTS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The ARexxGuide drawer of this archive contains 20 files that make up one
AmigaGuideĀ® application. The AmigaGuide files are:
ArexxGuide.guide ArexxGuide.guide.info
ARx_Cmd.ag ARx_Elements.ag
ARx_Elements2.ag ARx_Elements3.ag
ARx_Func.ag ARx_Func2.ag
ARx_Func3.ag ARx_Func4.ag
ARx_Index ARx_Instr.ag
ARx_Instr2.ag ARx_Instr3.ag
ARx_Intro.ag ARx_Notes.ag
ARx_Operator.ag ARx_PrgUcr.ag
ARx_UcrTutor1.ag ARx_UcrTutor2.ag
Only ARexxGuide.guide is intended as an AmigaGuide executable. The other
files are called from within the main node of that guide.
The following ARexx script files, located in the same directory, are used
to run interactive examples from ARexxGuide:
ARx_Cmpr.rexx ARx_IactExamples.rexx
ARx_Reg.rexx Arx_Trace.rexx
The 'Extras' drawer contains some files that are not necessary, but may be
helpful to some users. A Readme file in that directory explains those files.
The file 'UnCrunch.rexx' is the the source document for the program
included in the tutorial section.
INSTALLATION
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The ARexxGuide drawer can be moved to any location.
The #?.rexx files in the drawer may, optionally, be moved to the system
REXX: directory. The following command will do that:
copy <path>/ARexxGuide/#?.rexx REXX:
delete <path>/ARexxGuide/#?.rexx
RUNNING ARexxGuide
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
From the icon:
Double-click on the ARexxGuide.guide icon. ARexxGuide will open its
window.
The default tool in the icon is 'AmigaGuide' without path specification.
If your AmigaGuide executable program is located in a path that is
searched by Workbench, then that will be enough. If, however, AmigaGuide
cannot be found by Workbench, then you should single-click on the icon
and press Amiga-I. Add the full path to the 'Default tool:' field in
the Information window.
Example:
sys:utilities/Amigaguide
If you use Multiview instead of AmigaGuide, then you may need to change
the default tool.
When ARexxGuide is called from the icon, the .rexx interactive examples
will run, even if they are not moved to the rexx: directory.
From a shell:
You have more options when you run ARexxGuide from a shell, but may
also run into a few more problems because this guide uses multiple
files. When pressing one of the link buttons in the guide, AmigaGuide
will often look for one of the subsidiary files. It will find them if
they are in the current directory or if they are in a path included in
the AmigaGuide/path environmental variable.
--- Run ARexxGuide from the current directory.
Make the directory containing ARexxGuide.guide the current directory
before calling the guide:
Example:
cd <path>/ARexxGuide
Amigaguide ARexxGuide.guide
Interactive .rexx examples will run even if they are not moved to REXX:
when the guide is invoked this way.
--- Add the ARexxGuide path the AmigaGuide search path.
AmigaGuide will look for files in directories specified in the
environmental variable amigaguide/path. If you often run this guide from
a shell or directory utility, you should probably set the variable.
The following command, issued from a shell, will set a search path for
AmigaGuide:
makedir env:amigaguide
setenv amigaguide/path <path>/ARexxGuide
where <path> is the full path leading to the directory.
If you've already created an 'amigaguide' path in env:, then you may
omit the makedir command.
Note that this command will replace any value that might previously have
been set for the path variable. You can, however, include multiple paths
in that variable. Just separate each path from others with a space and
use the collection in the 'setenv' command.
The env: directory is located by default in RAM:, so this setting will
not survive a reboot. If you'd like to have path automatically set when
you reboot, issue this command:
copy env:amigaguide/#? envarc:
If that command is issued after you have opened and closed AmigaGuide,
then the window size and position last used will also be saved.
Once the search path for AmigaGuide is set, ARexxGuide can be run
without setting the current directory. The interactive examples,
however, might not run. They should be moved to the REXX: directory to
so that ARexx will be able to find them.
