index
ByVal

will be returned.
Discussion
This function returns the ASCII character code of the character at the position of the string that is
specified. If the second parameter is missing, position 1 is assumed. Note that if the index is less than 1
or larger than the number of characters in the string the return value will be zero.
Example
Dim s as String
Dim b as Byte
s = "Howdy"
b = Asc(s)
After execution, the variable b will have the value of 72 (48 hex), the character code for H.
Compatibility
BasicX does not support the presence of the second parameter.
