Hi,

I have a problem with my .mod.

enum Day {MON1, TUE1, WED1, THU1, FRI1,
MON2, TUE2, WED2, THU2, FRI2,
MON3, TUE3, WED3, THU3, FRI3,
MON4, TUE4, WED4, THU4, FRI4,
MON5, TUE5, WED5, THU5, FRI5 };

{Day} Mondays = {MON1,MON2,MON3,MON4};
{Day} Tuesdays = {TUE1,TUE2,TUE3,TUE4};
{Day} Wednesdays = {WED1,WED2,WED3,WED4};
{Day} Thursdays = {THU1,THU2,THU3,THU4};
{Day} Fridays = {FRI1,FRI2,FRI3,FRI4};
int MAX = 25;
range Weeks 1..5;

{Day} DaysOfWeekWeeks=[
{MON1, TUE1, WED1, THU1, FRI1},
{MON2, TUE2, WED2, THU2, FRI2},
{MON3, TUE3, WED3, THU3, FRI3},
{MON4, TUE4, WED4, THU4, FRI4},
{MON5, TUE5, WED5, THU5, FRI5}
];

struct HolidayTable {
string Remarks;
Day Day;
string Type;
};

{HolidayTable} HolidayTableRows from DBread(db, "select Remarks, Day, Type from HolidayTemp");

{Day} Holiday = {r.Day|r in HolidayTableRows};

I want to create another variable call AvailHoliday that does a symdiff of Holiday and Day but i'm not sure how

Hi,

OPL provides the set operations union, inter, diff, and symdiff

You should try something like :
{Day} AvailHoliday = Holiday symdiff Day

hmm seems to be getting this error

What is your opl version?
As far as I know, enum is not a keyword in OPL since the 4.0 version.

You must replace enums by {string} or set of tuple { string name};
For example:
{string} allDay = { "MON1", "TUE1", "WED1", "THU1", "FRI1"};
{string} Hol = { "TUE1"};
{string} mydiff = Hol symdiff allDay;
