Mainframe, Binary files

In jEdit a binary file like a 4680/4690-Register price change file looks like

Table View - Binary file

While in the RecordEditor Table-View, binary fields are converted to there text equivalent. It looks like

Record View - Binary file

To display a singe record in record view (as below), press the button to the left of the row on the "Table View - Binary file" screen.

Mainframe

The Record-Editor now supports editing native Mainframe Files on a PC. Only Fixed Block (RECFM=FB) files can be reliably transferred to and from the PC.

The system supports the following Mainframe-Binary formats
Format Cobol Picture Description
Zoned s999 Standard Cobol Pic s9(#) fields (where # is any number)
Packed Decimal s999 Comp-3 Packed Decimal
Binary s999 Comp Standard Mainframe Binary
Character XXX Standard Character fields

The system does not support Mainframe Floating point numbers (Cobol Comp-1 and Comp-2). Floating Point numbers are fairly rare in Cobol Programs.

Following is a Mainframe Binary File displayed on the Mainframe and in the RecordEdit Program on a PC.
