Appendix H. EBCDIC Chart
Extended Binary-Coded-Decimallnterchange Code (EBCDIC) The 256-position EBCDIC table, outlined by the heavy
black lines, shows the graphic characters and control char­ acter representations for EBCDIC. The bit-position numbers,
bit patterns, hexadecimal representations and card hole
patterns for these and other possible EBCDIC characters are
also shown.
To find the card hole patterns for most characters, parti­
tion the 256-position table into four blocks as follows:
1
3
2
4
Block 1: Zone punches at top of table;
digit punches at left
Block 2: Zone punches at bottom of table;
digit punches at left
Block 3: Zone punches at top of table;
digit punches at right
Block 4 : Zone punches at bottom of table;
digit punches at right
Fifteen positions in the table are exceptions to the above
arrangement. These positions are indicated by small num­ bers in the upper right corners of their boxes in the table.
The card hole patterns for these positions are given at the
bottom of the table. Bit-position numbers, bit patterns, and
hexadecimal representations for these positions are fouri.d in
the usual manner.
Following are some examples of the use of the EBCDIC chart: Character Type
