Odd Windows version
« on: October 08, 2005, 01:29:09 AM »

Hi all,

I was just wondering why the windows RF nightly build does not have ">" or "<"? Is there a reason for this? What minimalist trick am I missing that does not require ">" or "<" ?

Thanks,

Josef

< > are provided in the nightly build, but is not used for conditionals. It's a string construct used to define a sequence of code you want to run in the interpreter when the word that uses them is called.

Code:

| Example
|
| When "setup" is called, it'll create a constant
| named "myconstant" with a value of 100

: setup < 100 constant myconstant > ;

This is used in a few places in the bootstrap code, mainly the editor and "exit" for dealing with custom applications that hook into "ui"

Charles,

Since the common usage of > and < are used with if, like >if, <if, and =if, there really is not a need for > and <. To find the max or min, could just use the definitions in the ans library. Correct?
