Variable Declaration

Explicitly declaring variables helps expose errors, such as misspelled variable names. To make code more reliable and readable, use the Option Explicit statement in VBScript.

When you want to use strong variable typing, the logic should be programmed into a component built with a language that supports it, such as Visual Basic 6.0 or Microsoft Visual J++. Loosely typed variables (not typed until run time), such as variants in VBScript, can affect performance, especially when mathematical computations are involved.
