Successful project - excitement and thanks!

/*
* BUBBLE "MEETER" FOR TURNING OFF SOLENOID
*
* This program counts the number of "high" transitions on RB0 and if it is
* over a certain value (specified in code), it induces a high signal on RB1
*
* PIC16F628A
* 8 Mhz crystal, HS clock
*
* PORTB.F0, in : counter input
* PORTB.F1, out: run on signal
* PORTB.F2, in: Reset
*
* Author : Bruno Gavand, november 2005,
* The interupt routine used; the rest (including RS232 removed) and further
* modified by TJB; Feb08
