PICAXE Manual 2, page 23 - NCD is an added X1 and X2 feature.
I'm not sure if it will help in an LCD menu system; its detailed description is on page 24. It determines which highest bit is set in a variable, it is the equivalent inverse of the DCD command.
"w0 = DCD 3" set w0 to $0008, bit 3 set ( fourth bit )
"w1 = NCD $0008" sets w1 to 4, fourth bit is set ( bit 3 )

@tjconway,
you need to give more information about precisely what you are trying to achieve.
When 1 years ago now I wrote code to drive an LCD module out of a Siemens A55 mobile phone, I used the NCD and DCD commands for ease when using a 40X1. Those commands have been around for the 16 months that I have been using PICAXE.

Have a look at the code over 3 posts starting around post 36/37.
If this is the sort of thing you are trying to do then start at post 1 and read the entire history as I worked up a number of routines for basic fonts, drawings lines and circles, displaying graphs, creating a compass display and . . . .
Other members here (Tarzan? from memory) have created menu routines for standard LCD modules as opposed to gLCD modules.
