newRPL - build 1255 released! [updated to 1299]

[Gilles]

Claudio, did you think that a 'RETURN' command could be introduce in the future?
'return' exists in most langage and in PPL. The idea is to be able to exit a command/fonction at any time with the stack as it is, even in the middle of nested loops and IF/CASE.... I imagine this is not obvious because the program have to exit all and to deal with internal stuff in a proper way.

In fact, it could be seen as a kind of EXIT (wich is a advantage of newRPL vs RPL) but not only for a loop but for a full command/function. (or like a local KILL)

Usage case is :

Code:

a b START
 c d START
  MyStuff
  IF DidIgetIt? THEN MyResult RETURN END 
 NEXT
NEXT

Without RETURN and with EXIT you have to use a flag or a local variable and awfull things like :

Code:

1 CF
a b START
 c d START
  MyStuff
  IF DidIgetIt? THEN MyResult 1 SF EXIT END 
 NEXT
 IF 1 FS? THEN EXIT END
NEXT
IF 1 FS? THEN EXIT END
