Assignment ​

Structure ​

<variable> := <expression>

Example ​

Set a variable to a hard-coded value
pascal
procedure ScriptEvent (var Value : variant);
begin
Value := 10;
end;

This example sets the Value parameter equal to 10. In this case the value 10 is hard-coded.

Set a variable to the value of another variable
pascal
procedure ScriptEvent (var Value : variant);
var MyFloatVariable : double;
begin
MyFloatVariable := 10;
Value := MyFloatVariable
end;

This example sets the Value parameter to the value of the MyFloatVariable variable.

Set a variable to the result of a function
pascal
procedure ScriptEvent (var Value : variant);
begin
Value := TaxAmount(200,12.5)
end;

This example sets the Value parameter to the result of the TaxAmount function. Value is therefore set to 25 (200 * 12.5%).

Description ​

Assignment is used to set a variable to a value. The variable to be set is on the left hand side, the value to set it to is on the right hand side.

Assignment is performed using the := operator which is called the Assignment Operator. Note the colon proceeding the equal sign - it should not be confused with a = operator used to compare values (Refer Relational Operators)
