The character ÿ causes end-of-file

Postby zatlas1 » Fri Jul 20, 2012 3:37 am

Hi
I am getting ASCII text files and the FTP convert them to EBCDIC. Specifically the character 'ÿ' is translated to x'ff'. That should not be a problem but both in C and Rexx, when reading the file abruptly stop reading as if it was an unexpected EOF. Is that behavior normal and if so what could be done about it, short of translating the offending character to something else?

Thank you
ZA

Hello,

What does the record look like when viewed with HEX ON? And the next record?
Hope this helps,
d.sch.

I actually misstated the issue, the character at issue is x'ff' in the ASCII. Here is the section where that character appears in the original ASCII file:
Hex:
20 20 20 20 66 74 68 69 6E 67 0A 20 20 20 20 2A 2A 2A 20 46 61 69 6C 65 72 73 0A 20 20 20 20 5D 74 68 69 6E 67 0A 20 20 20 20 63 74 68 69 6E 67 0A 20 20 20 20 64 74 68 69 6E 67 0A 20 20 20 20 65 74 68 69 6E 67 0A 0A 2F 5E 5C 81 2F 0A 20 20 20 20 81 0A 0A 2F 5E FF 2F 0A 20 20 20 20 FF 0A 0A 2F 5E

so the hex code '2F 5E FF' was translated almost correctly to '61 B0 ..' and then the system does not see the rest.
