21. The bit pattern for each text character's raster image was maintained in RAM and could be modified by the user. 22. Other OASIS-supported geometric shapes having the record types POLYGON, TRAPEZOID, CTRAPEZOID, CIRCLE and PATH are defined by different bit patterns . 23. However, the internal representation of the null pointer may be any bit pattern ( possibly different values for different data types ). 24. This was useful specifically for paper tape, because punching the all-ones bit pattern on top of an existing mark would obliterate it. 25. For a RECTANGLE record, the bit pattern ( either a 1 ( enabled ) or a 0 ( disabled ) ) is: 26. The four output bit patterns that can arise corresponds to a specific logic type : PASS 0, YES, NOT and PASS 1. 27. In particular, the data bit pattern " 10001 " has a clock pulse inserted in the middle, where it would normally be omitted: 28. The standard forbids the use of the 10 / 3 12 / 1 bit pattern , in an attempt to eliminate the duplicate encoding. 29. The-127 and + 128 have the same eight-bit pattern , so the way it is interpreted is whether it is a signed or unsigned integer. 30. Reinterpreting this last bit pattern as a floating point number gives the approximation 2.61486 } }, which has an error of about 3.4 %.
