written in in ANSI 'C'. This makes it easy to port pForth to multiple
platforms. So far, pForth has run on Macs, PCs, SUNs, Amigas, Linux,
BeOS, Nokia Communicator, SGI Indys, 3DO ARM systems, 3DO PowerPC
systems, WebTV systems, Hitachi SH4, OpenTV prototypes, Compaq Ipaq
3970, Sharp LH79520 ARM processor, Ciena Systems networking hardware,
and some internal projects at Lucent.
Note: either use pforth_standalone binary, or add to .bashrc the line
alias pforth='pforth -d /usr/share/pforth/2.0.1/pforth.dic'
