Finding Length of Set

[Crystal]

How do I find length of a set?
For example:

Set
itemList 'Elements in the set' /n5 * n23/

Parameter
tot 'Total elements in the list'


tot = card(itemList)


What's wrong with this statement? Is there another command to find the
length of a set? Does anyone who a link to list of GAMS common
commands?

thanks.

Hi Crystal
Nothing is wrong, except that you have forgotten semicolons at the end of the statements

Set
itemList 'Elements in the set' /n5 * n23/;

Parameter
tot 'Total elements in the list';

tot = card(itemList);
display tot;
