The following shows the content of a record sequential file that has been sorted based on the character in position five (5) of each record. This example will use an ALTSEQ Table for an ASCII-encoded environment and will do a case insensitive sort....
The VSAM and QSAM Connection provides a suite of test programs describing the processing principles and techniques used for managing VSAM Data Sets, QSAM flat sequential files or Generation Data Groups (GDG) using COBOL, Assembler and other Utility progr
The INPUT PROCEDURE and OUTPUT PROCEDURE phrases are similar to those for a basic PERFORM statement. For example, if you name a procedure in an output procedure, that procedure is executed during the sorting operation just as if it were named in a PERFORM statement. As with the PERFORM statem...

(e.g., file, directory, etc.) that is required for the backup. By way of example, the first sorting algorithm can produce a single sorted element per pass (e.g., a bubble sort). After one such element is found, the located element is queued for backup to a backup system. In ...
Thing is, I like how the technology has progressed from WinForms to WPF to UWP to MAUI; the approach to coding visual design has improved immensely (well actually, this is a bit of a throwback to Cobol screen design…). Can I work without a designer? Yes...
