OPTION EXPLICIT statement

Purpose | Force explicit declaration of all variables.
Syntax | OPTION EXPLICIT
Remarks | Using OPTION EXPLICIT in a program has the same effect as using the #DIM ALL metastatement. That is, it requires that all variables be declared before they are used. When this option is used, the compiler generates a compile-time error if a variable or array is used without being explicitly declared.
