This Natural profile parameter sets the maximum value for the year part of date and time values that can be entered as constants or as terminal input.
Possible settings | 2699 |
The maximum year that can be entered is 2699 ; that
is, the maximum date value that can be entered is 2699-12-31 .

MAXYEAR=9999
changes the maximum date value that can be
entered from 2699-12-31
to 9999-12-31
.
Anmerkung:
Before setting the value for MAXYEAR
to
"9999", you should carefully check your application
for arithmetic operations or assignments of date or time values to fields that
have data formats other than date or time, and perform the necessary changes.
Otherwise, unexpected overflows leading to Natural errors at execution time may
occur. For example, you should check for
redefinitions of date/time fields with P6/P12 fields
assignments of date/time values to non-date/time fields such as
P6 := D
arithmetic operations with date/time values where the result is
assigned to a non-date/time field, for example: P6 := D + 7
input of date/time fields that is used in arithmetic operations with non-date/time fields later on, for example:
INPUT D(D) P6 := D + 1
The use of the Natural Engineer is recommended to check your application.
The setting of MAXYEAR
affects
checking of date/time constants by the compiler, for example: P6
:= D'2699-12-31'
INPUT
statements with input or modifiable date/time fields
MOVE
EDITED
statements with source or target date/time fields
IS
(D)
option in logical condition criteria
MASK
option in
logical condition criteria with four-digit year check (YYYY)
VAL
system
function with date field as target operand
You should ensure that the MAXYEAR
settings are
the same for
cataloging and executing a Natural application
Natural RPC servers and Natural RPC clients
