Option to report silent exception handling in LE

During some performance analysis we discovered in CICS trace a huge amount of S0CA - decimal overflow - interrupts caught and recovered by Language Environment. These were caused by a simple ADD statement in a cobol program which runs in an ILC en...

Enhance authentication APIs to support returning Identity tokens and accepting them for authentication

RACF recently (z/OS v2R4 and PTF'ed back to z/OS v2R2) added the ability for RACF to return identity tokens which are actually JSON Web Tokens (JWTs) and to be able to use them in lieu of a password for authentication. Can APIs, such as __passwd()...

Enable AUTOCVT to assume untagged files are ibm-1047

I have been porting several open source applications to USS using the -qascii option on the C/C++ compilers. This works wonderfully when auto conversion is also enabled. The one whole in the auto conversion feature is that it doesn't assume untagg...

Support record-wrapping in the z/OS C/C++ library

There is currently no option in the C/C++ library to wrap when writing data set records in "text" mode. The library *does* do this automatically for spool file data sets, but a line written to a regular data set that is longer than the maximum len...

Allow z/OS C/C++ library to write zero-length data set records using record mode processing.

The z/OS C/C++ library will currently not allow the creation of zero-length records using record-mode processing using fwrite(). This applies to RECFM=V*, and RECFM=U. It is possible using text mode, but this does not allow for binary processing. ...
