Re: Can a date have a *CYMD format?

[Brian Parkins <goodprophet.bp@xxxxxxxxx>]

Remember that date formats do not affect the internal representation of 
date variables. (Date variables/fields are always stored as a binary 
value.) The eight standard date formats, (e.g. *DMY, *ISO) indicate how 
a date variable should be presented for external interpretation.

That said, additional formats, (e.g. *LONGJUL and *CYMD) recognise that 
date values may be stored in character or numeric variables. These 
additional formats allow such values to be converted from 
character/numeric variables to full date variables - and vice versa.

In other words, *CYMD is provided for conversion to/from date variables, 
(using %DATE, %INT, etc.) - not for presentation.

Hope this helps.

Brian.
