ASC()

Description

Returns the ASCII value of the first character of a string literal or string variable.

Syntax

1. ASC(string$)
2. ASC("string literal")

Hints

If the string is an empty string the function will return 0.

Inverse function: To get the character the ASCII value refers to, use the CHR$() function.

Only ASCII values between 33 - 255 are printable characters.

Value 32 represents space. Values 0 - 31 are non-printable control and formatting characters.

Example

' Using a string literal
    print asc("A")               ' Produces 65
    print asc("Able")            ' Produces 65
    print asc(" ")               ' space - Produces 32
    print asc("")                ' special case of empty string - produces 0

' Using a string variable
    valueOfChar$ = "!"
    print asc( valueOfChar$ )    ' Produces 33

    valueOfChar$ = "!$#0@"
    print asc( valueOfChar$ )    ' Produces 33
    end
