It's not clear to me what you want to do but you could write the data to a
file and read that file from the shell script:

 set logging file input.dat

 define xyz
   set logging on
   printf "offset is %d\n", $offs
   set logging off
 end

However, perhaps we know that too.  AFAIK convenience variables are handled in
GDB just like ordinary program variables.  I don't think you can currently
regard the GDB command line as a program language but Daniel Jacobowitz is
working on something more powerful.

(gdb) help set environment
Set environment variable value to give the program.
