Warning
This item was deprecated in version 2019r2. Please use `String.AscByte` as a replacement.
## Description Returns as an `Integer`, the value for the first byte of a `String`. ## Usage *result*=**AscB**(*string*) **OR** Introduced 5.0*result*=*stringVariable*.**AscB** | Part | Type | Description | |----------------|------------------------------------|--------------------------------------------------------| | result | `Integer` | The value of the first character of *string*. | | string | `String` | Any valid `string` expression. | | StringVariable | `String` | Any variable of type `String`. | ## Notes The AscB function returns the code for the first byte in the `String` passed. If you need to get the character code of the first character of the string rather than the first byte, use the `Asc` function. AscB should be used instead of `Asc` when the string represents binary data or when your application will run on a one-byte character set (such as the US system) and you want case-sensitivity. ## Sample code This example uses the AscB to get the value of the first byte of the `string` passed. ``` xojo MsgBox Str(AscB("a")) ' returns 97 MsgBox Str(AscB("A")) ' returns 65 ``` ## Compatibility All project types on all supported operating systems. ## See also `Asc`, `String.ChrByte`, `String.IndexOfBytes`, `String.LeftBytes`, `String.Bytes`, `String.MiddleBytes`, `String.RightBytes` functions.
