I have an Array say A=(11,23,32,44,56,88,55,14,78,79) And B=(44,56,88,55,14) .Now using VBScript can I perform Set operation MINUS to get an other
No, vbs or vba cannot directly do a minus operation on two array ( no build-in function ) You must use loops and here is a good reference for array operations in vba http://www.cpearson.com/excel/vbaarrays.htm
