Michael,  Is it possible to extend this same set of functions to writing? Naturally I need to write back to the file now and the same problem presents itself. I have to search through other code bases to find a function or Google and find https://wiki.freepascal.org/File_Handling_In_Pascal which offers a whole host of options. SaveStringToFile from the wiki link wraps TFileStream but having a single low-level function would be best.
