But from what I understand Unidata does not produce compiled object code. It creates compiled P-Code, which is then interpreted at run time. True? False?

There is absolutely no reason to order code by frequency of usage in a non-interpretive (ie, compiled) language. When the object is loaded into memory, relocatable jumps are resolved, so it's as efficient to get to the last line as the first. > In the Sequoia version of Pick O/A it did matter.
