有關Visual Basic6.0問題

VB6有一個function 叫 asc他可以將char轉做ascii code, 例子如下:
dim intResult as integer
intresult = asc("a") ' it changes from a to 97

如想由ascii code轉回char, 可用chr這個function, 例子如下:
dim strChar as string
strChar = chr(97) ' it changes from 97 to a

用vb function Asc(character). e.g.
Asc("a") -> 97
Asc("0") -> 48
