For more informations look at: http://www.symbian.com/ -This is a port of Perl version 5.6.0 to EPOC. It runs on the Perl -Series 5, Series 5mx and the Psion Revo and on the Ericson M128. +This is a port of perl to the epocemx SDK by Eberhard Mattes, which +itself uses the SDK by symbian. Essentially epocemx it is a POSIX +look alike environment for the EPOC OS. For more information look at: +http://epocemx.sourceforge.net/ + +perl and epocemx runs on Epoc Release 5 machines: Psion 5mx, 5mx Pro, +Psion Revo, Psion Netbook and on the Ericsson M128. It may run on Epoc +Release 3 Hardware (Series 5 classic), too. For more information about +this hardware please refer to http://www.psion.com/ -Features are left out, because of restrictions of the POSIX support. +Vendors which like to have support for their devices are free to send +me a sample. -===================================================================== -Installation/Usage -===================================================================== +=head1 INSTALLING PERL ON EPOC -You will need ~4MB free space in order to install and run perl. +You can download a ready-to-install version from +http://www.oflebbe.de/oflebbe/perl/ -Install perl.sis on the EPOC machine (most likely a PSION Series 5, -5mx).

If you do not know how to do +that, consult your PsiWin documentation. -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.

The default -drive of perl is the same as the drive perl.exe is located on, the -default path seems to be '/'. +The built-in function EPOC::getcwd returns the current directory. -i.e. command lines look a little bit funny: +=head2 Restrictions of Perl on Epoc -D:\perl.exe C:/test.pl >C:/output.txt +Features are left out, because of restrictions of the POSIX support in +EPOC: -You can automatically search for file on all EPOC drives with a ? as -the driver letter.
