1、International Standard - only one of the positions 1, 2, 3, 4, 5, 6, 7 may be punched, which together with the NO PUNCH condition gives eight possibilities. These rules provide for 256 hole patterns (32 x 8). 4 Specification 4.1 Implementation of the 8-Bit coded character set Table 1 specifies for e

2、ach of the 256 8-bit combinations the corresponding hole-pattern. The columns and rows are numbered in binary and decimal notation. Each position in table 1 is identified by its column and row number (for example 06/11) and by the corresponding bit combination (for example 0110 1011, where the most

3、signifi- cant bit is on the left). 4.2 Implementation of the 7-Bit coded character set The hole-patterns shown in the first half of table 1 (i.e. columns 00 to 07) apply to the 128 7-bit combinations, which are obtained ignoring the most significant eighth bit (bs).
