140 | \&\s-1EPOC\s0 is an \s-1OS\s0 for palmtops and mobile phones. For more informations look at: | |
141 | http://www.symbian.com/ | |
142 | .PP | |
143 | This is a port of perl to the epocemx \s-1SDK\s0 by Eberhard Mattes, which | |
144 | itself uses the \s-1SDK\s0 by symbian. Essentially epocemx it is a \s-1POSIX\s0 | |
145 | look alike environment for the \s-1EPOC\s0 \s-1OS\s0. For more information look at: | |
146 | http://epocemx.sourceforge.net/ | |
147 | .PP | |
148 | perl and epocemx runs on Epoc Release 5 machines: Psion 5mx, 5mx Pro, | |
149 | Psion Revo, Psion Netbook and on the Ericsson M128. It may run on Epoc | |
150 | Release 3 Hardware (Series 5 classic), too. For more information about | |
151 | this hardware please refer to http://www.psion.com/ | |
152 | .PP | |

154 | me a sample. | |

157 | You can download a ready-to-install version from | |
158 | http://www.oflebbe.de/oflebbe/perl/ | |
159 | .PP | |
160 | You will need at least ~6MB free space in order to install and run perl. | |
161 | .PP | |
162 | Please install the emxusr.sis package from | |
163 | http://epocemx.sourceforge.net/ first. | |
164 | .PP | |
165 | Install perl.sis on the \s-1EPOC\s0 machine. If you do not know how to do | |
166 | that, consult your PsiWin documentation. | |
167 | .PP | |
168 | Perl itself and its standard library is using 4 \s-1MB\s0 disk space. | |
169 | Unicode support and some other modules are left out. (For details, | |
170 | please look into epoc/createpkg.pl). If you like to use these modules, | |
171 | you are free to copy them from a current perl release. | |

183 | .Sh "Restrictions of Perl on Epoc" | |
184 | .IX Subsection "Restrictions of Perl on Epoc" | |
185 | Features are left out, because of restrictions of the \s-1POSIX\s0 support in | |
186 | \&\s-1EPOC:\s0 | |
187 | .IP "\(bu" 4 | |
188 | socket \s-1IO\s0 is only implemented poorly. You can only use sysread and | |
189 | syswrite on them. The commands read, write, print, <> do not work for | |
190 | sockets. This may change iff epocemx supports sockets. | |
191 | .IP "\(bu" 4 | |
192 | kill, alarm and signals. Do not try to use them. This may be | |
193 | impossible to implement on \s-1EPOC\s0. | |

197 | binmode does not exist. (No \s-1CR\s0 \s-1LF\s0 to \s-1LF\s0 translation for text files) | |

199 | \&\s-1EPOC\s0 does not handle the notion of current drive and current | |
200 | directory very well (i.e. not at all, but it tries hard to emulate | |
201 | one). See \s-1PATH\s0. | |
202 | .IP "\(bu" 4 | |
