LE individual modules CEEROPT and CEEUOPT should be treated the same

CEEROPT and CEEUOPT allow for the passage of LE options at the individual job/application level. However, currently CEEROPT and be loaded from STEPLIB while CEEUOPT requires that it be linked with the application/program. CEEROPT is for region lev...

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. ...

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...

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...

Specify NONOVR for RUNOPTS at the application level

We would like a way to specify NONOVR at the application level (CELQUOPT CEEXOPT), similar to the region level https://www.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.ceea500/clfdop64.htm#clfdop64Currently, the NONOVR/OVR are not...

Provide an option to prevent RPTSTG(ON) from internally resetting the initial stack size

When RPTSTG(ON) option is set, LE resets the initial stack size to 1MB for 64-bit applications. This is fine for code in which LE automatically expands the stack when needed, however for generated code (as in JavaScript code from Node.js) in which...

Extend CEEENTRY to support Debug Tool "Delayed Debugging"

Actually Language Environment Assembler Programs do not support Debug Tools Delayed (or Deferred) debugging due to the fact that the CEEENTRY macro does not register for "New Program Entry Point Event" as is done for LE Enabled COBOL, PLI and C/C+...

Function fseek should offer the same performance on FBS data sets regardless of how many volumes they are stored on.
