Apple][e/PD/BOB/ARMBOB/doc/!BobDoc/Run

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

<H2>How to run ArmBob programs</H2>
When the !Armbob application 
<IMG SRC="!Sprites#!ArmBob">
has been seen, or 
has been filer_booted, four new filetypes are defined:
<UL>
<LI><A HREF="#BobFile">
<IMG SRC="!Sprites#file_04a" ALT="filetype 04a" ALIGN=MIDDLE>
 BobFile</A>
<LI><A HREF="#BobTask">
<IMG SRC="!Sprites#file_04b" ALT="filetype 04b" ALIGN=MIDDLE>
 BobTask</A>
<LI><A HREF="#BobProj">
<IMG SRC="!Sprites#file_04c" ALT="filetype 04c" ALIGN=MIDDLE>
 BobProj</A>
<LI><A HREF="#BobPTask">
<IMG SRC="!Sprites#file_04d" ALT="filetype 04d" ALIGN=MIDDLE>
 BobPTask</A><BR>
</UL>
Double-clicking on files of these types will cause them to run.
Files of any of these types can be edited by holding down SHIFT and 
double clicking on them. They can be created initially as text files, 
with their filetypes altered later from the filer menu, or as blank 
files of the appropriate type, created by filling in the filetype 
in the blank option of Edit's <EM>Create </EM> Submenu from the
iconbar.
<P>
Double clicking <KBD>!ArmBob </KBD> 
<IMG SRC="!Sprites#!ArmBob" ALT="">
sets up the BobFile, TaskBob, BobProj and BobPTask 
filetypes and their run actions, and opens a filer window on a 
directory for holding Armbob programs. The path prefix to this 
directory is <KBD>Bob:</KBD>. It also turns off trace and debug
mode. To debug or trace it is more convenient to run the program 
in a taskwindow (just change the filetype). Debug or trace mode 
is enabled by double-clicking the relevant Obey files.
<P>
Armbob programs are run by first being compiled into an intermediate
code for a virtual stack-machine, which is then invoked to run the
code. Compiler errors cause a window to open with an error message.
Clicking on the <KBD>throwback </KBD> icon causes the relevant source file
to be displayed in an edit window, with the error line highlighted. 
Runtime errors do not do this (yet!).

<H3>
<A NAME="BobFile">BobFile Programs </A>
<IMG SRC="!Sprites#file_04a" ALT="filetype 04a" ALIGN=MIDDLE>
</H3> 
BobFiles are analogous to Basic files. Double click on 
them to make them run (in a command window, unless a mode 
change command is given). Everything should be run from 
within the desktop. There is no Armbob equivalent to the 
Basic interface (with the Basic prompt &gt; ).
<HR>
<H3>
<A NAME="BobTask">BobTask Programs </A>
<IMG SRC="!Sprites#file_04b" ALT="filetype 04b" ALIGN=MIDDLE>
</H3>
BobTask files run in a taskwindow when double clicked. 
They are only appropriate for programs with textual 
input and output. For graphics use a BobFile.
<HR>
<H3>
<A NAME="BobProj">BobProj Programs </A>
<IMG SRC="!Sprites#file_04c" ALT="filetype 04c" ALIGN=MIDDLE>
</H3>
BobProj files are appropriate for large programs 
stretching over many files. They contain a list of 
the program files (which might as well have the 
text filetype). Double click on a BobProj file to 
compile and run in a command window the program 
contained in the files that it lists.
Click here for the syntactic <A HREF="#rules"> rules </A>
for BobProj files.
<HR>
<H3>
<A NAME="BobPTask">BobPTask Programs </A>
<IMG SRC="!Sprites#file_04d" ALT="filetype 04d" ALIGN=MIDDLE>
</H3>
BobPTask files are appropriate for large programs 
stretching over many files. They contain a list of 
the program files (which might as well have the 
text filetype).  Double click on a BobPTask file to 
compile and run in a taskwindow the program 
contained in the files that it lists.
Click here for the syntactic <A HREF="#rules"> rules </A>
for BobPTask files.
<HR>
<H4>
<A NAME="rules">Rules for Project Files</A>
</H4>
<UL>
<LI>Lines whose first non blank character is | are comments.
<LI>Non comment lines should have the pathname of a file for first
   word. Blank lines are permitted (version 2.1 onwards).
<LI>Files which create an instance object of a class must be preceded
   by files defining the class.
