I didn't understand initially what "pass by name
means". Probably had to
look more careful at the program.
I didn't think you did. Its a common mistake made by people trying to
port ALGOL-60 programs who don't understand ALGOL-60 semantics. I just
wanted you to be aware since you were porting to C++ and you could have
inadvertently introduced bugs if you had incorrectly re-coded any
semantic which relied on the pass-by-name convention of argument passing
in some other section of the code.
"pass by reference" and "pass by value" are the 2 semantics
implemented
by most modern programming languages, and you chose one of the few old
languages which does "pass by name" instead.
Doesn't matter any more. I need to do a statement: this thread is
closed
from now. Ones more: thanks everybody for your responses!
Good luck with your new code.
