Conversion of COBOL programs to PL/1

The online system for displaying and maintaining mainframe data stocks is primarily a technical instrument for ensuring the quality of the data. This is often only possible if there is an opportunity to access the data without an application's technically focused user interface. With the exception of DB2 data stocks, almost all the file formats on the mainframe can be edited according to the user's authorization (e.g. IMS databases, ISAM, VSAM and QSAM files). Converting the application from COBOL to PL/1 is aimed at standardizing the programming languages for mainframe applications to make PL/1 the leading language. In order to keep the effort of defining conversion rules to a minimum, manual revision of the generated programs is connected to an automatic conversion of the online programs, with the help of a Perl script. The conversion of the SDFII screens to PL/1 takes place by regeneration.
