The following example displays the characters A through J and uses ASC( ) to display their corresponding ANSI values.

STORE 'ABCDEFGHIJ' TO gcANSI && 10 characters

?? ASC(SUBSTR(gcANSI, nCount)) && Display ANSI value
ENDFOR

vb的函数，不需要包含头文件。
Dim MyNumber
MyNumber = Asc("A") ' Returns 65.
MyNumber = Asc("a") ' Returns 97.
MyNumber = Asc("Apple") ' Returns 65.
