For more informations look at: +http://www.symbian.com/ + +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. + +=head1 INSTALLING PERL ON EPOC + +You will need ~4MB free space in order to install and run perl. + +Install perl.sis on the EPOC machine (most likely a PSION Series 5, +5mx). If you do not know how to do that, you are on your own. + +Perl itself and its standard library are using 2.5 MB disk space. I +left out unicode support modules and modules which will not work with +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. + +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. When perl is running, you will see +a task with the name STDOUT in the task list. + +=head1 USING PERL ON EPOC + +=head2 IO Redirection + +You can redirect the output with the UNIX bourne shell syntax (this is +built into perl rather then eshell) For instance the following command +line will run the script test.pl with the output redirected to +stdout_file, the errors to stderr_file and input from stdin_file. + +perl test.pl >stdout_file stderr_file + +Alternatively you can use 2>&1 in order to add the standard error +output to stdout. + +=head2 PATH Names + +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. + +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. + +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 searches for C:\a.txt, +D:\b.txt (and Z:\a.txt). + +=head2 Editors + +A suitable text-editor can be downloaded +from symbian http://developer.epocworld.com/downloads/progs/Editor.zip + +=head2 Features + +The built-in function EPOC::getcwd returns the current directory. + +=head2 Restrictions + +Features are left out, because of restrictions of the POSIX support in +EPOC: + +=over 4 + +=item * + +backquoting, pipes etc. + +=item * + +system() does not inherit ressources like: file descriptors, +environment etc. + +=item * + +signal, kill, alarm.
