Introduction
EPOC is a OS for palmtops and mobile phones. For more informations look at:
http://www.symbian.com/
-This is a port of Perl version 5.005_63 to EPOC. It runs on the Perl
-Series 5, Series 5mx. I have no reports about the Psion Revo, the
-Ericcson (??) and the Psion NetBook. I only have acess to an Series 5.
-
-Features are left out, because of restrictions of the POSIX support.
+This is a port of perl to EPOC. It runs on the Psion Series 5, 5mx,
+5mx Pro, Psion Revo and on the Ericson M128. I have no report about
+the Psion Netbook or the S7. For information about this hardware
+please refer to http://www.psion.com.
=====================================================================
Installation/Usage
this version. (For details look into epoc/createpkg.pl). If you like
to use them, you are free to copy them from a current perl release.
-Copy eshell.exe from the same page you got perl to your EPOC device.
-Start eshell.exe with a double tap.
+Get ESHELL from symbian:
+http://developer.epocworld.com/downloads/progs/Eshell.zip
Now you can enter: perl -de 0 in order to run the perl debugger. If
you are leaving perl, you get into the system screen. You have to
-switch back manually to eshell.exe When perl is running, you will see
+switch back manually to ESHELL. When perl is running, you will see
a task with the name STDOUT in the task list.
======================================================================
PATH Names
======================================================================
-Pathnames to executables in eshell.exe have to be written with
-backslashes '\', file arguments to perl with slashes '/'. The default
-drive of perl is the same as the drive perl.exe is located on, the
-default path seems to be '/'.
+ESHELL looks for executables in ?:/System/Programs. The SIS file
+installs perl in this special folder directory. The default drive and
+path are the same as folder the executable resides. The EPOC
+filesystem is case-preserving, not case-sensitive.
+
+EPOC uses the ?: syntax for establishing a search order: First in C: (RAM),
+then on D: (CF Card) and last in Z: (ROM).
+
+The perl @INC search path is now implemented with '?:'. Your perl
+executable can now live on a different drive than the perl library or
+even your scripts.
-i.e. command lines look a little bit funny:
+ESHELL paths have to be written with backslashes '\', file arguments
+to perl with slashes '/'. Remember that I/O redirection is done
+internally in perl, so please use slashes for redirects.
-D:\perl.exe C:/test.pl >C:/output.txt
+perl.exe C:/test.pl >C:/output.txt
You can automatically search for file on all EPOC drives with a ? as
-the driver letter. For instance ?:\a.txt seraches for C:\a.txt,
+the driver letter. For instance ?:\a.txt searches for C:\a.txt,
D:\b.txt (and Z:\a.txt).

Editors
======================================================================
-You may have a problem to create perl scripts. A cumbersome workaround
-is to use the OPL Editor and exporting to text.
+A suitable text-editor can be downloaded
+from symbian http://developer.epocworld.com/downloads/progs/Editor.zip
+
+====================================================================
+Features
+====================================================================
-The OPL+ Editor is quite good. (Shareware: http://www.twiddlebit.com)
-There is a port of vim around:
- http://www.starship.freeserve.co.uk/index.html
+The built-in function EPOC::getcwd returns the current directory.
======================================================================
Restrictions
======================================================================
-The following things are left out of this perl port:
+Features are left out, because of restrictions of the POSIX support in
+EPOC:
+ backquoting, pipes etc.
directory very well (i.e. not at all, but it tries hard to emulate
one) See PATH.
-+ sockets seems to work now!
-
+ You need the shell eshell.exe in order to run perl.exe and supply
it with arguments.
You will need the C++ SDK from http://developer.epocworld.com/.
You will need to set up the cross SDK from

You may have to adjust config.sh (cc, cppflags) for your epoc
install location.
