EDX Utility Programs Overview
In the 1980s Legler Systems Company designed, developed and marketed two
utility programs specifically for the IBM Series/1 mini-computer to improve
programmer productivity using the Event Driven Language (EDL).
IBM Series/1 EDX Software:
The EDXREF and EDXDMP
utility programs are useful in maintaining existing source code and debugging EDL programs
running under all versions of EDX operating system. These utility programs
have been installed at over 100 customers throughout the country.
Later, the EDXCPY and EDXPC
utility programs were developed to print the content of disk or tape records and
to download text files to a pc connected to the Series/1 mini-computer via the
asynchronous communication feature 2091/2092
or Feature-Programmable Multiline feature 2095/2096.
These EDX utility programs are written in the EDL programming language
for easy maintenance and portability. Both executable and source code are
provided.
IBM Series/1 Computer Hardware:
During the product life cycle of the IBM Series/1 computer, over 100,000
computers were sold worldwide by IBM representatives and business partners.
We had one of those IBM Series/1 computers (model 4955-F) with 9-track tape
drive (4969), hard disk drives (4963), remote bi-sync and acca communication
support over dial-up and leased telephone lines to provide the following
computer services: (a) low cost batch, (b) remote computer processing and (c)
diskette file conversion (EBCDIC to ASCII).
IBM Series/1 Programming:
Legler Systems provides custom EDL programming, software maintenance and
application development for the IBM Series/1 computer on a contract basis.
