Hello i have a source text file with ansi encoding written using Macintosh (CR) containing a sequence of EOT,EOT NUL characters every 1024 bytes.
I need to read this file and convert it to a string. I tried to open it in stream mode, and used the filereadex to put the content in a blob variable. Anyway when i try to convert the blob to a string i get it truncated before the first NUL character.

li_FileNum = FileOpen(ls_nomefile, streamMode!, Read!, LockWrite!,  Replace!)
eRet = FileEncoding(ls_nomefile)          
li_bytes = FileReadEx(li_filenum, bdata)
ls_string = string(bdata, eRet)

Is there a simple way to remove the NUL characters and get the whole file in a string variable?

Hi Simone;

      Strange enough, I just solved this issue with my new daughter in-law's MAC computer. When you create a file on the MAC, the binary content is not compatible with MS-Windows based PC's. What I needed to do was have her use a USB that I formatted using the FAT format. Once the MAC saw the device where the file was being created as Windows FAT format, it wrote the file using MS-Windows binary encoding. From there, I was now able to open and process the file datum via PB.

HTH

Regards ... Chris
