Re: "extract" command enhancement

[Paul Jackson <paulgjackson@xxxxxxxxx>]

OK, here's another idea.

Leave EXTRACT as is: add few more bifs:

%DAY
%MONTH
%YEAR
(maybe %CENTURY)

allow for free format use:

D DateField         S            D  DATFMT(*ISO)
D Day               S         2 0

to get portion of date:

Eval Day = %DAY(DateField)

to change portion of date:

Eval %DAY(DateField) = 01

repeat as for %MONTH, %YEAR, (%CEN) etc.
