This is not correct.  Epsilon DOES allow compiling or shell interaction in
a window, similar to many EMACS-like editors for Unix(tm).  It is true that
PC-DOS does not support multitasking.  As a result, Epsilon itself must
simulate the missing functionality, intercepting the PC-DOS interrupts and
multiplexing the CPU between Epsilon and the shell, etc.  This only works
for "well-behaved" programs which do not similarly preempt the interrupt
vector, or write directly to the screen memory, but the shell and most
compilers, linkers, simple file utilities, etc. will work.

[BTW: No version of Epsilon is in the public domain.  Epsilon is a copyrighted
product of Lugaru Software Limited.]
