4 # vms: file(1) magic for VMS executables (experimental)
6 # VMS .exe formats, both VAX and AXP (Greg Roelofs, newt@uchicago.edu)
8 # GRR 950122: I'm just guessing on these, based on inspection of the headers
9 # of three executables each for Alpha and VAX architectures. The VAX files
10 # all had headers similar to this:
12 # 00000 b0 00 30 00 44 00 60 00 00 00 00 00 30 32 30 35 ..0.D.`.....0205

15 0 string \xb0\0\x30\0 VMS VAX executable

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