Abstract

A method is described which provides a tool to interpret, format, and print or display data from IBM Personal Computer (PC) Network SNA 3270 Emulation trace files. The IBM PC Network SNA 3270 Emulation program provides the ability to trap and save all SNA Path Information Units (PIUs), sent or received, to an operator-specified file. This information may then be used to analyze communication problems. These SNA Path Information Units are variable-length structured fields with coded sub-fields which are very difficult to follow if presented in an unformatted manner. The Trace Analyzer tool separates and presents individual SNA PIUs as separate paragraphs, and leading fixed-length fields common to each PIU are at a fixed indent level.
