Note that the two numbers '''11''' and '''12''' are not considered a range.
===version
This REXX version isn't limited to integers. It doesn't need a magic number to terminate the list.
<lang rexx>/*REXX program creates a range extraction from a list of numbers (can be negative.) */
Line 4,635:
new: 0-2,4,6-8,11,12,14-25,27-33,35-39

<!-- elided version 1a as it was slower and less idiomatic.
===version
The REXX version is the same as above, but doesn't modify a '''do''' loop's index ('''j'''),
<br>and it also doesn't need a magic number to terminate the list.
Line 4,656:
