SetUB Function

Format

i = setub(month, year, maximum_cmc);

Description

The setlb function returns the upper bound of the century month code (CMC) of an event. The arguments month, year, and maximum_cmc are all numeric expressions.

If the month and year are both valid, the function returns the CMC of that date, as if calling:

i = cmcode(month, year);

If the month is invalid but the year is valid, the function returns the CMC of December in the valid year, as if calling:

i = cmcode(12, year);

If both the month and year are invalid, the function returns the upper bound represented as maximum_cmc.

Return Value

The function returns the upper bound of the CMC of an event.

Example

if CM12Y < 9997 then
ldoblc = setlb(CM12M, CM12Y, 0);
udoblc = setub(CM12M, CM12Y, 9999);
endif;
