Mainframe selection contains scripts and programs that were selected mainly as code patterns to illustrate some of the capabilities of several MF programming languages, and to suggest a consistent programming style facilitating code maintenance and modifications.
"Consistent" is a key word here — almost any style is as good as any other — once the consistency is provided. It is important to note that the same coding style can be used with quite different programming languages, making it easier to switch between them. If you'll look at other programming examples on this site, you'll see the illustarion of the above statement — the same coding style throughout, which is only slightly adjusted to accomodate the specifics of the corresponding language.
However, each script or program is not a mere exercise in a code styling — it provides on most part a useful function that is debugged to the best of my ability and is normally tested by several years of intensive usage. This is not to say that it is in any way guaranteed to be error-free — you will be using any code you pick from this site entirely at your own risk and will be completely responsible yourself for any problems, which might arise from this usage. So when trying code, please exercise the common sense precautions and test code most thoroughly yourself before applying it to anything serious.
This legal mantra been chanted, I want to mention that all error reports and any comments about my code are most welcome, and I'll try to do my best to fix any known problem as quick as I'll be able to do this.
