Safely getting out of an interrupt

[Charlie]

A safer approach is to simply have the interrupt set a flag and return. You main program can be a tight loop that checks flags. When to detects the flag, it GOSUBs to the new location.

;Interrupt Processor:
ASM
INT_LIST  macro    ; IntSource,  Label,     Type, ResetFlag? 
        INT_Handler   INT_INT,   _OK,       PBP,  yes   ;USART CS
        INT_Handler   AT1_INT,   _Fire,     PBP,  yes   ;Fires Coil
        INT_Handler   IOC_INT,   _Wipe,     PBP,  yes   ;Fires Output
        INT_Handler   RX_INT,    _Grab,     PBP,  yes   ;USART Transmission Received
        INT_Handler   T1G_INT,   _Get_RPM,  PBP,  yes   ;Count Pulses to Determine RPM
        INT_Handler   TMR3_INT,  _Stall,    PBP,  yes   ;RPM Below Limits of TMR1
    endm
    INT_CREATE                      ;Creates the interrupt processor
ENDASM

This is a typical DT_INT Declaration. As you can see, when an external interrupt occurs the program jumps to a Label called "OK". When an Angular Timer Interrupt occurs it jumps to "Fire". Each Interrupt has a different Label the DT_INT INCLUDE will sent the PC to. An IOC INT directs the PC to "Wipe", and so forth. This may be the part you missed based on your comment,

"All I'm after is to transfer to a location other than where the INT occurred."
