Invisible Assumptions in Mainframe Software Engineering: Teams need to look for hidden risks and blind spots they don’t realize they have. In the world of mainframe development, invisible assumptions can lead to hidden risks and blind spots that teams often don't realize they have. These assumptions can be costly, as you can't test what you can't see. Understanding and addressing these hidden traps is crucial for maintaining the stability and reliability of legacy systems.

We are excited to announce that Colesoft Marketing Inc has officially joined the Izzi Software family!

we have started publishing z/XDC's Built-in Help as web pages that are far more user friendly than z/XDC's classic HELP command. The pages contain the same topics as the classic Built-in Help, but they have several additional features:

The XDCADATA utility filters ADATA files to remove excess ADATA. When properly set up, size reductions up to 90% or more could be achieved. Two changes have been made, one to make it easier to identify DSECT maps to be excluded, the other to increase the size reduction even more!

Starting with update DBC-2302H, c/XDC users will notice two things: They will quickly notice that the CWIDE and C80 profiles no longer display a LIST VSTACK command in their Watch Window. They will also notice that STEP commands (PF9, PF10 and PF11) no longer perform sluggishly. These two facts are related.

Just as classic z/XDC can access dataspaces in live storage, so can dump/XDC access dataspaces contained within a dump. Also like classic z/XDC, dump/XDC uses ALETs for accessing dataspaces.

At long last, we have turned our attention to the long languishing LIST RSA command and brought it forward into the modern era!

We have made major changes to the processes for performing both maintenance updates and initial product installs: WRT initial installs, we have completely done away with the use of SMP/E. Now the process is a straightforward unTERSE of an XMITs collection library followed by an XMIT-RECEIVEs job to create the several Product Libraries. WRT maintenance updates, these now do full replacements of all Product Library content. This means that the product shipment package for both initial installs and maintenance updates is the identically the same file for both purposes.
