Example
ASCIICode = Asc("A")    // Returns 65
ASCIICode = Asc("Barbier")   // Returns 66
Syntax
<Result> = Asc(<Character String to Process>)
<Result>: Integer
Requested ASCII code (between 0 and 255).
Windows Mobile This code is included 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 an empty buffer, <Result> will be equal to 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

Extracting a string (via the [[ and ]] operators) can be used to convert a character found anywhere in a string.
For example: "Asc(Str[[N]])" returns the ASCII value of Nth character found 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 character in UNICODE format.
To find out the ASCII code of a character in UNICODE format, this character must be converted into 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

Operating mode in GO mode and at run time

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