When fixed-length records are written in text mode, records are padded with blanks if the record length is larger than a line, and if the blankstrip processing attribute is enabled. (When sending data from MVS, blankstrip strips trailing blanks. When sending data to MVS, blankstrip pads the records with blanks).

If you are writing data to a fixed record length MVS data set in text mode with blank stripping enabled, and the data contains blanks at the end of the line, an I/O error occurs. This is because the server is not able to return the blanks to the client when the file is read back.

If you get an error message when trying to create or access an MVS data set, see Network File System messages for further explanation of the message.
