Datalight C provides library routines to intercept any interrupt, and
cause a specified C function to be executed. The return code from the C
function can be used to specify whether the previous vector can be
'chained' to or not. Source code is provided for the library routines,
I imagine they could be easily adapted to MSC.

Datalight C is $99 and available from (206) 367-1803.
