I set a group indicator to be TDS mnemonics <FS> for a message containing a special byte X'1c'. But the parsing always fails at the byte. If I change the special byte to be any other ASCII char, the parsing is fine.
Testing messages are put through MQInput node, which has CCSID set to 437 and encoding set to 273. And environment is WBI MB 5.0 CSD 3 in Win2K.
Any idea? |

Did you try specifying the value in Unicode format?

| Yes, indeed, I tried <U+001C>. It does not work either. |

| What platform are you running on. I have heard that <FS> on Windows is x1A, and x1C on other platforms. |

Thanks for your reply. Problem solved!
IBM conversion tables usually do this if they convert between a "DOS" (or
Windows or OS/2) codepage and one for a different platform.
The idea is that ISO defines 0x1A to be the SUB character, but on
DOS/Windows/OS/2 systems, 0x1A==^Z is used in text files as "end of file".
Therefore, IBM decided for DOS codepages to "rotate" several control
codes. Instead of a simple swap of two codes, three codes were rotated.
ISO semantics IBM DOS
1A SUB 7F
1C IS4 1A
7F DEL 1C |
