# vms: file(1) magic for VMS executables (experimental)
#
# VMS .exe formats, both VAX and AXP (Greg Roelofs, newt@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:
#
# 00000 b0 00 30 00 44 00 60 00 00 00 00 00 30 32 30 35 ..0.D.`.....0205
# 00010 01 01 00 00 ff ff ff ff ff ff ff ff 00 00 00 00 ................
#
0 string \xb0\0\x30\0 VMS VAX executable
>44032 string PK\003\004 \b, Info-ZIP SFX archive v5.12 w/decryption
#
# The AXP files all looked like this, except that the byte at offset 0x22
# was 06 in some of them and 07 in others:
#
# 00000 03 00 00 00 00 00 00 00 ec 02 00 00 10 01 00 00 ................
