SPECIFICATIONS FOR A GENERAL PURPOSE BCD UNPACK MODULE FOR SINGLE TIME STEP, REPETITIVE MODE, INTEGER DATA.
Abstract
This module will unpack blocks of BCD data where each block contains a time sample and n data samples where n is less than or equal to 225. The maximum number of computer words per block of input will be less than or equal to 151. Under parameter control the module will process any number of files per tape, skip initial files, skip initial records within the file before processing, and process any number of sequential input tapes. Under parameter control the program will output a variable number of files and tapes. Parameters will specify the number of BCD characters in the time sample and the data samples, the number of data samples per block, the sign bit position, and whether a 1 bit is plus or minus. Output will be on tape with one BCD sample per computer word. All bit shifting required to unpack the data will be performed in FORTRAN.
