How do I calculate a future date?

I am sure this is an easy one (if you can find the function) but I have not been able to find it in the help ...

I want to calculate ... Future date = (Today + X days)

NextCallDate = (DateSys() + 1)

I tried the above and it returns 200906301

which is appending the number one to the end of the date which is being stored as YYYYMMDD.

What is ... or where can I find the command to calculate the future date?

Any help is always appreciated

Dan, you have several options

NextCallDate = IntegerToDate(DateToInteger(DateSys()) + Xdays)

or

dTmp is date = DateSys()
dTmp..day += Xdays

Note:
dTmp..Day = dTmp..Day + XDays will generate a runtime error - direct assignment is not allowed - see the help for more info

Hey Dan

Date..Day -=7

or

Date..Day +=7

Hi Dan,

Some more info:
Originally Windev started with dates only in string format. Later they added the date type.
Datesys() returns a string, so if you add "1" to it. you will get a concatenation of two strings. As Arie and Dennis stated, you can perform direct calculations on the date type. For the traditional string type date you have to use functions like integertodate.

Thank you to all ...(Arie, Dennis, & Piet)

Arie, your first explanation was exactly what I was looking for ...

Dennis, I had no idea you could do anything like that, very efficient

Piet, thanks for the explanation, your explanation about DateSys() being a string help things make sense.

Again, Thank you all for your help!!!

Just for info, WD initialize most variable types. For a date or an hour
variable, it's initialized to the current date or time.
So "dToday is date = Today()" is equal to "dToday is date"

Hi,

Yes, that can be tricky sometimes, so don't forget to initialize a date type after declaration to "" if needed.
