Algorithm for EDAP-extracting data and plotting

EDAP (extracting data and plotting), an APL program driven by a REXX exec, is described. It runs in two modes. In a disconnected service machine environment, where, for example, three systems in one department use it to monitor the manufacturing lines and the semiconductor tools. In this mode, it runs unattended 24 hours a day seven days a week. It can also be used interactively. Given an arbitrary file, with numerical region buried in it, the program uses an elaborate algorithm to find the numerical region and then plot composite multi-region graphs in seconds. The algorithm falls in the area of pattern recognition. A brief overview of the algorithm is given
