Does that mean *I'm* "ancient"? Nah!!!! <G> Multiple question marks means multiple passes to interpret the value. ??20?? means to take the contents of parameter 20 and use that as a parameter number. So on the first pass through the code given above, parameter 4 is checked for being equal to L. Then parameter 7 is checked for being equal to L, then parameter 10. (Assuming that parameter 20 is not changed except in the code shown.) evaluate and multi-pass interpretation gives the capability to process parameters like an array, rather having to code for each individual parameter.
