Nearly all implementations of Forth offer unix like shell services. For instance, one can issue shell commands from SwiftForth:
~/frt/SwiftForth$ bin/linux/sf SwiftForth i386-Linux 3.4.5 03-Oct-2012 $ ls bernd.f~ bnf.fs~ doc lib mbrad.f sievebench.fs~ bin brad.f fib.f LICENSE mbrad.f~ src ok
Bigforth, gforth, Vfx Forth have equivalent methods of calling shell services. How to do external shell calls from SP-Forth, running under Linux? I suppose that one can call a dynamic library service to do the magic. Is there a library in the devel folder that I can include, in order to call the unix shell?
