According to Wikipedia this version of the OS is considered in the public domain.
The following source was extracted from a DASD volume provided by Jay Moseley. See http://www.jaymoseley.com/hercules/compilers/mvtsource.htm
The above webpage and DASD volume are included in this repository for future reference and use.
The code is written in assembler.
The source datasets are:
- MVTSRC.CB545 - ALC source
- MVTSRC.LM546 - ALC source
- MVTSRC.COBOL.MACLIB - macros required to assemble the source
- MVTSRC.COBOL.CNTL - jobstreams to assemble, link, delink, and run a test compile
- MVTSRC.COBOL.LISTINGS - listings from the assemble and link jobs
The following extensions have been used for the source:
