The maximum record length is understood to be the length of the longest record (net record length in bytes) not including the record length fields.
Because openFT can also transfer files using unicode character sets one must distinguish between length in bytes and length in characters.
In BS2000 and z/OS files, the maximum record length is stored as a file attribute in the catalog (with variable-length records and an additional allowance of 4 for the record length field).
In Unix systems, Windows systems and POSIX systems, you can set the maximum length of your file which you wish to transfer as text or record-structured binary file (user format) individually. The prescribed maximum record length must be at least as large as the largest one actually available, otherwise the FT request cannot be executed.
Please note that the maximum record length must be observed not only on the sending and receiving system but also during transfer. In the case of a transfer in the UTF-8 character set (see section “Data conversion”), the record length needed during transfer may be larger than the record length on the sending or receiving system.
