CalcIt Commands

Converts the string representation of a date to its numeric format. The converted date is returned in parameter DateAsNum, if the input date is valid.

The function returns TRUE if the date is valid or FALSE if it is not.

This functions is useful in cases a CalcIt code accepts input from the user, e.g from a Form and need the dates to be validated without stopping the execution of the program (with error) as will be the case with the use of the more straightforward function STRDATE to do the same job.

if(ValidDate('32/12/2005',v));
 print('Numeric representation: ',v);
else
 print('Invalid Date');
end;
