List Commands Library for 50g

[John Keith]

Excellent, David! SPLIT is impressively fast for integers and even faster for strings.

Your above explanation is enlightening and illustrates well the power of the Library.

I have another little program here which finds all the Kaprekar numbers up to 1000:

Code:


\<< 0. 1 1000
   FOR n n DUP SQ DUP SIZE 2. / IP SPLIT + SAME
      { 1. + n SWAP } IFT
   NEXT \->LIST
\>>

Takes about 42 seconds (less than one second on the emulator), which is 2-1/2 to 3 times as fast as my best program using previous versions of the Library. Without ListExt commands it would be very slow indeed.
