I need to program a hi select block that looks at four analog in's and outputs the highest....Can anyone help??? Thanx !!!
 
Are you thinking of the SEL function (part of the PCFL, Process Control Function Library) that is available in Quantum and 984-685/785 processors?

This function can compare up to 4 values (16 bit word, double precison word, or floating point) and output the highest, lowest or average.
