CALL 43 returns the current date and time as a string. PUSH the number
of the string to receive the date/time (dd/mmm/yy HH:MM:SS). You must
allocate a minimum of 18 characters for the string. This requires you to set
the maximum length for all strings to at least 18 characters.
Example:
u10 STRING 100,20
u20 PUSH 1: CALL 43: REM put date/time in string 1
u30 PRINT $(1)
u40 END
CALL 44 returns the current date on the argument stack as three numbers.
There is no input argument to this routine and three variables are returned.

u10 REM DATE RETRIEVE – NUMERIC EXAMPLE
u20 CALL 44: REM INVOKE THE UTILITY ROUTINE
u30 POP D,M1,Y : REM GET THE DATA FROM THE 30 STACK
u40 PRINT “CURRENT DATE IS”, Y,M1,D
