# vms:  file(1) magic for VMS executables (experimental)

# VMS .exe formats, both VAX and AXP (Greg Roelofs, newt (a] uchicago.edu)

# GRR 950122:  I'm just guessing on these, based on inspection of the headers
# of three executables each for Alpha and VAX architectures.  The VAX files
# all had headers similar to this:

# The AXP files all looked like this, except that the byte at offset 0x22
# was 06 in some of them and 07 in others:
