Stored procedures
Returns the ASCII code of the specified character. The ASCII code used corresponds to the ANSI standard used in Windows.
Example
CodeASCII = Asc("A")    // Retourne 65
CodeASCII = Asc("Barbier")   // Retourne 66
Syntax
<Result> = Asc(<Character string to process>)
<Result>: Integer
ASCII code (between 0 and 255).
<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 the ASCII code of the first character.
  • a buffer, <Result> will be 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(Ch[[N]])" returns the ASCII value of the Nth character of the string "Ch".
