How To Read Half width & full width characters from EBCDIC using Cobol copy book

Question

I am using Talend to convert EBCDIC file using Cobol copy book representation of EBCDIC file. but i am unable to find out Half width and Full width representation of EBCDIC character

please suggest.

Answer 1

I am using cobol copy book to read the EBCDIC, so COM-4 is right data type for reading Half width as well as Full width data. COM-3 is used to read packed decimal values

Answer 2

You can find documentation for one of the most widely used code pages for EBCDIC at Wikipedia. I am unfamiliar with the idea of half width vs. full width EBCDIC. Perhaps the EBCDIC 930 encoding for halfwidth Katakana is what you have in mind?

Answer 3

Are you talking about double-byte character sets? They use a shift-in and shift-out character x'0e' and x'0f' (if I recall correctly). You will need to parse the fields as a stream and, literally, shift into double byte mode when you hit the x'0e' and return to single byte mode when you hit the x'0f'.
