Re: [MiNT] Correct XBios function ID for VsetMask?

[Miro Kropáček <miro.kropacek@gmail.com>]

Well, on the other hand, my version (which was converted to hyp; April 1994) says 92 (0x5C).

My copy of the Compendium (the printed one) says 150 (0x96).  Which version of
the Compendium are you referring to?  Also, the official Atari Falcon
documentation (available on the Atari docs site) says VsetMask is 150 (0x96).

VsetVars is an undocumented opcode, but is implemented in Falcon TOS as opcode
92 (0x5c).

It would seem that AHCC, VBCC, and your copy of the Compendium are incorrect.
