BIC Machine Instruction Support Added

We have just published update Z22-1709E to add to z/XDC release z2.2 support for the new BIC machine instruction.

CFRIENDLY operand added to the LIST LKEDMAP command

It turns out that c/XDC users have reasons to issue the LIST LKEDMAP command a lot. This is because:

  • It sometimes is the case that the external name of a function differs from its internal name,
  • And it is sometimes the case that the user needs to provide a function’s external name in order to load the right source image map,
  • And normally, AUTOMAP would do the job for you, but sometimes you might want to load a map or two that AUTOMAP would not be able to realize you might need.

RMODE64 Support Now Available for z/XDC z2.2

I have just uploaded update Z22-1707B.* It implements the following in z/XDC:

RMODE64 support: When z/OS R2.3 comes out, it will have support for loading modules into above-the-bar storage. z/XDC is now ready to fully support mapping, displaying and stepping through such modules.

A Bug in the Z21-1509H Maintenance

It recently came to our attention that under certain circumstances, attempting to use XDC in task mode FRR debugging causes the address space to hang at a pause. Turns out we had a bug in the Z21-1509H maintenance that allowed an incompatible TCB to be selected and used. This caused the “unpause” to never occur and things end up at a standstill.

System Symbol Support Implemented in server/XDC

This will interest Sysprogs who have to install and maintain the VTAM network nodes that cs-cdf/XDC needs.

I have just posted Z21-1509F that adds System Symbol support (&SYSCLONE &SYSNAME and friends) to server/XDC’s parsing of its //SYSIN parameter file.

c/XDC is Coming!

As many of you know, for many years, ColeSoft has been working hard on bringing our XDC product into the C C++ *AND* Metal C worlds! Well, at long last it looks like were finally there!

Maintenance Z21-1506C

I’ve just published update Z21-1506C that fixes a problem in the vector support introduced in Z21-1505F. We were using an incorrect flag bit in one of our vector support checks. Oops! That causes a S0C7-FE abend to pop up when starting a debugging session for a SRB.

Vector Register Support Now Available in z/XDC

I’ve just finished publishing update Z21-1505F. It implements vector register support in z/XDC. Vector registers are now saved and restored by z/XDC for both task mode and SRB mode execution.

For Those of You Who Need to Debug Intercepts and Exits Inside Dynamic Allocation

We’ve just now pushed out an update (Z21-1505E) that adds support for a //xxxNOALC DD DUMMY jcl statement. When this ddname is present in the TIOT, z/XDC will abort any command or internal service that attempts to use Dynamic Allocation (SVC 99).

We want to thank Bob Edmond of BMC Software for requesting this feature.

FTP Downloads for Maintenance Now Available

A couple years ago, we discovered that we had posted some bad maintenance and we had no way of knowing how many times it was downloaded and who had done the downloading. To help deal with this, we built an interface that requests some basic user information, just a name and email, before the maintenance file can be downloaded. This process gives us a list of users that we can contact in case of an error in the maintenance or an older maintenance has been superseded.
