[mod.computers.vax] redirecting output

I've been compiling and running some ISSCO/DISSPLA programs using the
      CALL REGIS(3,1) subroutine which sends the graphics output (REGIS)
to my vt241 terminal. 

I would like to capture these regis commands in a file but our release
of ISSCO subroutines does not allow this. The package does allow one
to create a meta file though, but this gets you no further ahead since
DISSPOP - the program to interpret the meta file - also does not include
the desired feature.

I've tried many experients in redirecting output including:

1. $ @comfile/out=regis.out         where: comfile=$ run issco_program

2. $ DEFINE FILE.NAME SYS$OUTPUT
   $ RUN ISSCO_PROGRAM

3. $ DEFINE/USER FILE.NAME FOR006


All three experiments yielded the same result: the TEXT diagnostic messages
were captured in the file, BUT NO REGIS COMMANDS.

The one experiment that DID work, was:

$SET HOST/LOG=FILE.NAME 0

which keeps a log of the entire login session. This file DID have the regis
commands in it.

My question is this: what does SET HOST 0 do that the other 3 methods don't?

Has anyone else tried anything like this?
