Syntax: A = DATE(n)

Function: Returns the month, day, day of week, or year from the optional real time clock

Mode: Command, Run

Cards: All. Note exceptions for RPC-52.

DESCRIPTION

A DS1216DM must be in the RAM socket. Consult your hardware manual for location. A numerical value

of the month, day, or year is returned. The program under the TIME function is used to convert numerical

date to a string. Substitute DATE for TIME in the program. STR function 10 also converts a number to a

string.

A HARDWARE error is returned if the RTC is missing or bad. Use the ONERR construct to trap a defective

DS1216DM. Hardware error code at address 101H is 50.

Day of week is returned only on cards w hich use a DS1216DM clock module. (This exc ludes t he R PC-5 2.)
