Epic and ARM

The UNIX version of EPIC software requires an ANSI-C compatible compiler and has been reported to run on SGI IRIX, Sun4OS4, Solaris, BSD, Linux, HP-UX and AIX.

Installing the software

For installation of the latest version (under academic license or software evaluation license) read the file README and get the file EpicArm.1.2.2.tgz. Academic and software evaluation licences are included with this software. (See the README).
A previous version is still available as EpicArm.1.1.2.tgz

Getting started

First, find out about EPIC. As example, you can study the files in EP/examples/bincalc, a binary calculator that features a (rudimentary) parser. Compile the module numbers.ep as follows:

epic numbers.ep

This yields new files numbers.arm and numbers. The latter is an executable shell-script that loads the arm interpreter with the former arm program, and reduces prefix terms on its standard input to its standard output:

user> echo "plus(i,i)" | numbers
jxt(i,o)
user>

When called with several .arm, .ep and .rnx files, the compiler will leave the .arm files alone, compile the .ep and .rnx files, and generate a script that loads all relevant .arm files.

Furthermore, when epic is called with the -S option, the generated script will lift standard input to EPIC string representation, and apply the function ppp_bincalc to this lifted string. At the moment, type-checking of external functions is not working correctly, with the -Q option, type-checking is skipped altogether.

epic -S -Q io.ep numbers.arm bincalc.ep

Now you can use the syntax defined in io.ep:

user> echo "101*101" | bincalc
11001
user>

Type
