Example

ASCIICode = Asc("Barbier")   // Returns 66
Syntax
<Result> = Asc(<Character string to process>)
<Result>: Integer
ASCII code (between 0 and 255).
Windows Mobile This code is between 0 and 65535.
<Character string to process>: Character, character string or buffer
Character whose ASCII code must be calculated. If this parameter corresponds to:
  • an empty string or buffer, <Result> will be 0.
  • a character string, <Result> will be equal to the ASCII code of the first character.
  • a buffer, <Result> will be equal to the ASCII code of the first byte.
WEBDEV - Browser code In this version, this parameter can only correspond to a character or to a character string.
Remarks

Extracting strings

You can extract a string with the [[ and ]] operators to convert a character at any position in the string.
For example: "Asc(Str[[N]])" returns the ASCII value of the Nth character in the "Str" string.
Windows Mobile

UNICODE and ANSI

About 30 specific characters have a different ASCII code according to their format (UNICODE or ANSI).
Asc returns the ASCII code of a UNICODE character.
To get the ASCII code of an ANSI character, the character must be converted to ANSI (UnicodeToAnsi) before calling Asc.
For example:
Charact1 = Charact(128)     // Returns "€"
Charact2 = Charact(8364)      // Returns "€"
Code1 = Asc("€")            // Returns 8364
Code2 = Asc(UnicodeToAnsi("€"))     // Returns 128
Windows Mobile

Differences between GO mode and runtime

In GO mode (simulation on the development computer), when Asc is called, the ASCII code returned corresponds to the ASCII code of the ANSI character.
For example, when the following code is executed:
Code1 = Asc("€")
  • in GO mode, this code returns 128.
  • at runtime, this code returns 8364.
The differences between GO mode (simulator) and runtime are presented in Differences between GO mode and runtime.
