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...

Allow modification of CEEDUMP naming convention via parms

Currently, there is no means to change the CEEDUMP naming convention. The LE code uses /path/CEEDUMP.date.time.PID or /path/FNAME.date.time.PID, which may not match the convention a customer uses for other trace and dumps in Java. Providing such a...

LE storage report STACK64 option new feature

The Maximum used by all concurrent threads is to count active thread number which is counted after thread initialization before thread termination and could handle the workload. We need one thread number statistics value align with the stack lifet...

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. ...

Allow HEAPZONES LE RTO to be set in CEEBXITA Assembler Exits

As documented in the z/OS Language Environment Programming Guide: You cannot set HEAPZONES at the system level, region level, or in the CEEBXITA assembler user exit interface. This RFE documents the need to allow HEAPZONES to be specified in CEEBX...

z/OS LE/C should support to freopen() for SYSIN dataset open

System:z/OS v.2.1Description:While the SYSIN DDwhen defined with DATA or * are JES subsystem managed, in XL C, SYSIN DDwill be treated as the C stream stdin, regardless of how it is sourced(subsystem or data set), and is treated special. The freop...

Unexpected CEELAA_STACKFLOOR64 address when storage initialization is used

During testing of IBM Fault Analyzer for z/OS, we encountered a problem with the CEELAA_STACKFLOOR64 field. Fault Analyzer uses this value to determine the valid address range of the stack storage when checking a possible DSA address. Basically, i...

Code examples needed for the "fldata() ? Retrieve file information" topic in z/OS XL C/C++ Runtime Library Reference

A comment came in while user was viewing a XL C/C++ z/OS KC page saying "links retrieved in top Google search, website is clear, fast and responsive, but not enough code samples". Specifically, they were looking at https://www.ibm.com/support/know...

Remove macro expansion branch instruction opcode dependencies from LE runtime routines

At least one LE runtime function (CEEVTOVF) uses branch instruction opcodes within macro expansions (at least EDCPRLG) to determine the language of the caller and bases actions on that language. Assembler macros IEABRC and IEABRCX interfere with t...
