CORCAS compares the cases who perform different modules (groups of tasks). It determines the "core" set of cases which perform each module based on the average task importance in the module for each case. CORCAS uses the Case Title file created by MAKCFL to describe the core cases.

Program Invocation
The specific syntax for program invocation varies between operating systems. This document diplays the code for the AIX version.
opt: Program Options (none currently supported) ssss: The study number icd: Input Case Data file ict: Input Case Title file itf: Input Task Factor file (contains task clusters) itt: Input Task Title file
CORCAS Control Card
CORCAS: cc 01-06 The literal 'CORCAS' study: cc 08-11 The study number for this run title: cc 13-72 The report title for this run.
CUTOFF Control Card (optional)
CUTOFF: cc 01-06 The literal 'CUTOFF'
ncut: cc 08-11 Maximum number of core cases to report for each module
(default = 96).
ptpcut: cc 13-16 Minimum percent of tasks performed in the module to be
considered a core case (default = 33.3)
aticut: cc 18-21 Minimum average task importance in the module to be
considered a core case (default = 50.0)
Module Selection Cards
These cards specify the modules to be compared. Up to 100 module cards may be specified. There must be a membership (MBR) and a co-performance (COP) factor available on the Task Factor file for each specified module.
module: cc 01-06 The module ID
title: cc 08-67 Optional module title. If blank, the module factor title
will be used.
These cards are terminated by an end-of-file or an '@eof' image.
