Read and Writing Windows Files from UniVerse/UniData
Reading and Writing to Windows files is pretty simple within MultiValue Database application This article talks about SUBROUTINE (Store procedures) that can be used to make your job easier. The routines included in this article have a few limitations that you need to be aware of, though. They will read the complete Windows Files into memory as a dynamic array. This is not a problem with small files, but if you are working with large file (3MB, 4MB, or 10MB), it can become a problem. If you need to work with large files, then you will need to read the file in chunks, which is another article all together.
Another limitation has to do with binary data or blobs. MultiValue Database are designed to handle business data for storage, processing, reporting, mining, as well as other business tasks. Since binary data is unstructured and is generally stored in the OS File System, not the database, MultiValue SUBROUTINES (stored procedures) don't handle them well. If you want to know how to work with and store binary data within a MultiValue database, the please see the articles relating to Binary/Blob data.
