My port of Larn 12.0, based on Don Kneller's port from Unix to MSDOS, used
GEMDOS calls for console I/O. According to the MWC documentation, these can
easily be redirected. I suspect they meant "by a command shell." The simple
fix for your case would be to write a small loader program that understands
how to do redirections. This program would just have to close the three
stdio descriptors, 0-2, open the AUX: device, and use Fdup or Fforce to set
0-2 to the same as the AUX handle. Then Pexec Larn from there. You could do
this in C, which would be easy, but if you're tight for memory space you
might want to code this in assembler instead.
