(SWI &20)
Entry
R0 Vector number
R1 Address of releasing routine
R2 Value given in R2 when claimed
Exit
R0 Preserved
R1 Preserved
R2 Preserved

Use

The purpose of this call is to remove a routine from the list of those that claim a vector.

Notes

This removes the routine, which is identified by both its address and workspace pointer, from the list for the specified vector. The routine will no longer be called.

If more than one claim is made with the same parameters, only the first one to be called is removed.
