the difference between VBScript and JavaScript

When you invoke VBScript or JavaScript subroutines from an ASP file written in VBScript, you can use the keyword "call" followed by the subroutine name. If the subroutine requires parameters, you must surround the arguments with parentheses when using the keyword "call". If "Call" is omitted, the argument does not have to be surrounded by parentheses. If the subroutine has no arguments, then the parentheses are optional.

When you call VBScript or JavaScript subroutines from an ASP file written in JavaScript, you must use parentheses after the subroutine name.
