Re: Fgets and ascii-ebcdic

The original environment describes a mixed character encoding where the results are correct. The ASCII 0x09 is the Tab character which maps to the EBCDIC 0x05 Horizontal Tab (HT) character.

If that is understood, yet the original intent from the OP is not progressed by that comment, some more comments that might be worth review...

Using "rb" giving more than one line is also correct because binary data can not have line control characters, since no byte should be interpreted as anything other than the code point it is. However, I believe "type=record" may be used to /trick/ binary open to treat the data as record oriented; that may require using fread() instead.?

Since apparently the stream file is tagged with CCSID 1252, then the concern can be resolved by specifying on the open "o_ccsid = 1252".

For either case above, the program that reads the data, if that program will also write the concatenated data, it must only concat data which has already been converted to the CCSID(1252) in order to maintain the integrity of the STMF having been tagged with that encoding. That is, for the string 'ROSE' in EBCDIC to be appended to the 0x0109, the x'D9D6E2C5' must be converted to the ASCII x'524F5345' before writing that full string x'0109524F5345'.
