- # 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

- 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:
