OCLC Tape Conversion Project

摘要

This paper explains the design and use of a program to convert 9-track OCLC tapes (in modified MARC format) to 7-track tapes. The 9-track tapes are written in an 8-bit expanded ASCII character code, and the 7-track tapes are written in a 6-bit code derived from the 8-bit code. These codes are un-recognizable by the machine; hence the need for this program. (Author)
