Use CALL 43 to retrieve the current date and time as a string.
Input and Output Arguments
This routine has one input argument and no output arguments. The input
argument is the number of the string to receive the date/time (dd/mm/yy
and hh:mm:ss). You must use the STRING statement (see page 11 -37) to
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.
