[comp.windows.x] Alarm call error with Xtank

Erich_S_Proudfit@cup.portal.com (05/09/91)

 
I've been compiling Xtank on a Data General AV300.  I've gotten the compile to
go ok, but when I select any of the play options (Standard, Players, Robot, 
Customized), the screen clears back to the window I ran xtank from and the
message Alarm call appears.
 
Can anyone tell me if this is a 'C', OS or X error message or what it is so
that I can debug the code or do whatever I need to to clear the message and
play the game.
 
Thanks in advance
