Why you should care

[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]VB has specific behavior that enable the developer to use variables even if these variables have not been previously declared and typed. However, it is possible to avoid this default behavior using the Option Explicit : in this case, all variables will require a declaration prior use.
This provides 2 main benefits.
The first benefit is a lower memory consumption improving other all application’s performance. This is due to the fact that undeclared variables are automatically created as Variant (large memory consumption).
The second benefit is that this option helps the developer to detect typing errors when writing code. [/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]

Business Impacts

Option Explicit is recommended because it greatly increases productivity and makes the code more efficient and less consuming.

CAST Recommendations

Option Explicit is recommended for VB users as it allows for improving the business aspects of the application portfolios that are developed in the company.  As such, Option Explicit should be utilized in the company’s style guides that encourage developers to focus on lowering memory consumption and improving performance for their respective applications.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]
