1. A display management apparatus for causing a display unit to display N candidate values selected from integers in a target range having a predetermined base value as the maximum value, as candidates to be selected by a user, the display management apparatus comprising: at least one memory operable to store program code; at least one processor operable to read said program code and operate as instructed by said program code; first selection code configured to cause the at least one processor to generate a a list comprising a plurality of values that are multiples of a plurality of different reference values without intermediate values, from among the integers in the target range as candidate values, by performing an operation on the base value and the plurality of different reference values; display control code configured to cause the at least one processor to cause the display unit to display a candidate value list that lists N candidate values that include the list comprising the plurality of values selected by the first selection code; and value management code configured to cause the at least one processor to manage the value of each of a plurality of types of variables serving as distribution destinations of the base value, wherein the display control code is further configured to cause the at least one processor to cause the display unit to display a value selector and a value confirmer for each of the plurality of types of variables in a state in which the user can specify, and when the user specifies the value selector, to display the candidate value list; and when the user specifies the value confirmer, the value management section adds a candidate value selected from the candidate value list by the user to the variable corresponding to the value confirmer, wherein N is greater than 1, and the plurality of candidate values are simultaneously displayed in the candidate value list before the user select the candidate value.
