Most snippets consists of relatively few lines of code, particularly since they focus on accomplishing a single task.

Creating a Top 100 QBasic list is a bit challenging in that it is used to create both graphical and non-graphical applications. Should the Top 100 list reflective an essentially non-graphics language such as Perl, or should the Top 100 list mirror the snippets for a' graphics-intensive language such as the .NET family of languages?

I find that my opinion continues to shift on about 10%-20% of the list, so don't be surprised to find the list changing - or growing as I consider the list in more detail.

You can view the snippets online at this site or download my freeware gbCodeLib code librarian, which has the source code for all of these. It contains snippets and mini-tutorials for QBasic as well as several other languages such as VB, VB.net, VBA, JavaScript, Perl, Java, and HTML.

For now, the list favors DOS/command line capabilities, although for gaming support I am looking to add more graphical capabilities to the list.
