Personally, it's a tough call.

Yes, they were designed to be loaded from a single file:
"call \usr\lib\tscontrol.udf"

But - with over 1000 lines, separate posts makes it easier to digest and review the individual functions.

I guess we need to discuss the difference between a UDF and a UDF-Library of many related UDFs.

Thanks..
