Type conversions

Former Member — Mon, 10 Dec 2007 09:47:54 GMT

Hello,

How is type conversion done in a statement like

DATA: date type d,
      string(10) type c.
date = string + 1.

If string has the value "20071031", will 1 be added as a string (resulting in "200710311" which is then somehow converted to a date), like a number (resulting in "20071032" which is then somehow converted to a date) or like a date (resulting in "20071101")?

Regards,

Christoffer

Did you try typing it and running it?

DATA: date TYPE d,
      string(10) TYPE c.

string = '20071031'.

date = string + 1.

WRITE: / date, string.

Result: 00000000, 20071031.

( the intermediate result of "string + 1" will be 20071032, as it will be converted to a numeric for the "+1" operation ).

Hey here nothing will come to Date.

The type conversion is not possible.

Why do you believe it's not possible?

There are three types involved: characters, date and integer. Conversion rules exist between all of these types.

Hi,

Conversion rules exist between all of these types. but straight away u can not do this.

if the string is first converted as date field and then incremented

date = string .

date = date + 1.

u can get the result as 20071101

if string id incremented first and then u convert as date field u can get

string = 20071032 and date = 20071032 (not recommended )

the case u have discussed is not possible i think.
