empty (blank) lines in ASCII files sent from Linux to z/OS (MVS) in text mode are converted to x'25' values. The target file is an FB 80 file. The correct translation would be to convert the empty lines in the ASCII files to a blank line on z/OS. If the following was in an ASCII file: This is the first line The next line will be converted to x'25' on MVS This is the last line, but it will end up starting with x'25' on MVS. I can work around this problem by sending the file through: sed - e 's/^$/ /' This converts empty lines to lines with 1 space. The ASCII to EBCDIC conversion will work correctly with the target of recfm F files. I have not tested to see what would happen to recfm V files. I do know that the standard ftp client on Linux performs the conversion correctly. I am running perl v5.8.8 built for X86_64-linux-thread-multi. Thank you.
