Darrel,
I recently replaced the On Interrupt code in an existing program with the RX_INT and it works great.The code was reduced by 127 words and I was able to eliminate a interrupt anomaly I sometimes experienced.Though compilation was successful,I would get a warning "Temp variables exceeding T4",which was generated in the ReEnterPBP.bas.I found what caused it in my code was this long comparison evaluation "if (fwd_cycle_comp = 1 and portb.4 = 1 and portb.2 = 1 and porta.0 = 1) or (datain1 > 1638) then".If I shortened the code the warning disappeared.Since everything was working fine I commented out the error routine for T4.I am using the latest Mplab and PBP.
Thanks & Good Job
