GN_Ldm, Localized Date Manipulation

Register parameters

RST 20H, DEFW $8009

IN:
A = desired string with
     A7 = 1 get day of the week
     A6 = 1 get month name
     A5 = 0 full string, 1 short string
     A4 = 0 get moment (no short string available)
     A0-A3 day of the week from 1-7 (Monday-Sunday)
           or month name 1-12 (January_December)
           or moment : 1=today, 2=yesterday, 3=tomorrow

HL = Destination buffer (at least 16 bytes required)
     HL has to be in segment 2 or 3

OUT, if call successful:
     Fc = 0
     HL = null terminated string desired
     DE = zero at the end of the string
     B = number of characters written to buffer (except trailing zero)

OUT, if call failed:

Fc = 1

A = error code

Registers changed after return:

...C..HL/IXIY same

AFB.DEHL/.... different

Notes

The call is useful to get country localized full or short string of day of the week or month name. An example of the usage can be read in Calendar popdown source code.

The localized string of 'Today, Yesterday or Tomorrow' is available. It is used by GN_Sdo to output today instead of formatted date as seen in Index application.

The buffer on entry has to be in segment 2 or 3, segment is used by the Date Filter Definition Table (FDT).
