Very well put, as usual.
One other thing you can do is use the __log() function to show how a
string is being interpreted:
i.e. instead of:
${__function(P1,P2)}
try (spaces inserted for clarity):
${__function( ${__log(P1)} , ${__log(P2)} )}
This will log the value of P1 and P2 to jmeter.log.
or indeed
${__log( ${__function(P1,P2)} )}
which will log the output of the function.
The __logn() function is exactly the same as __log(), except it
returns nothing, so it could be used as follows:
${__logn(P1)}${__function(P1,P2)}
HTH.
