Guy Harris (talk | contribs) →GE600 series: Periscope up! As shown by the sample code linked to, it doesn't require recursion, just iteration, and, for a fixed-size item, you can unroll the loop. Clean up links and add a period to the end of a sentence. |

Line 73:
Also present is unusual (variable-bit-length) byte load and store instructions that use ''byte pointers'' for memory operands: in modern terminology these are bit-field insert and extract. In addition to a word address, the bit length (S) and the bit offset (P) of the byte from which to load or into which to store are specified. These instructions can specify a byte size of 0-36, but a byte may not straddle a word boundary.{{sfn|pdp10|pages=2{{hyp}}85-2{{hyp}}89|loc=Byte manipulation|}} The string manipulation,{{sfn|pdp10|pages=2{{hyp}}91-2{{hyp}}99|loc=2.12 String Manipulation|}} BCD/binary conversion,{{sfn|pdp10|pages=2{{hyp}}98-2{{hyp}}103|loc=2.13 Decimal Conversion|}} and string editing{{sfn|pdp10|pages=2{{hyp}}104-2{{hyp}}112|loc=2.14 String Editing|}} instructions in later models use byte pointers and have the same restrictions.
