Abstract |
The paper describes a program, RETRIV, written to be used in conjunction with the Air Quality Data Handling (AQDHS) system. When used in conjunction with a catalogued procedure, it is possible to run the statistics program, the report program, the National Aerometric Data Bank (NADB) input program, or combinations of the above with a single set of retrieval control cards. When used alone, RETRIV will purge the AQDHS master file of unwanted data, obtain a listing of site location data from the AQDHS master file, prepare retrieval control cards for the report program, or select data for specialized processing. Sufficient flexibility has been built into the program to make it widely useful. (Author) |
