>Does anyone know how to get a segment moved from a USL file into an XL file?
 
As someone else pointed out, USLs contain only compatibility mode code, and
XLs contain only native-mode code. You'll need to do one of two things:
 
1. Rewrite the USL routine in a language for which you have an NM compiler, or
 
2. Write a switch stub, which is a small piece of native mode code that can
   call the emulator and run compatibility mode code. You'll also need to put
   the code that's in the USL into an SL using SEGMENTER. Switch stubs need
   to be written in Pascal or C, since those are the only languages on the
   HP3000 that support pointers. As long as you have a Pascal compiler (or
   have access to one) and know the calling sequence of the routines that
   you have in your USL, you can use SWAT -- the Switch Assist Tool -- to
   write the code for you. SWAT is in PUB.SYS and is a simple VPlus
   application. It's documented in the Switch Programming Manual.
 
If the routine that's in your USL is written in COBOL, it's probably easiest
just to compile the source with a native mode compiler. Switch stubs are a
bit harder to write for COBOL programs, and some COBOL subprograms can't be
accessed that way at all.
