LE

C fopen() fails with errno 41 for VSAM VRRDS files; EDC5041I An error was detected at the system level when opening a file.

We have products that use the VSAM VRRDS file type. We would like to use Java and the JZOS Toolkit to open and read these files while remaining zIIP eligable. The JZOS Toolkit uses the C fopen() to open VSAM files and this fails for the VRRDS file...

When forming CEEDUMP truncated the names of the entry points. Printed only the first 64 characters. CEEDUMP must contain a fully qualified entry point names.

64-bit version of CEE3ERP required

CICS TS 4.2 and above provide support for Java by running a JVM within a 64-bit PIPI enclave (CELQPIPI). Every thread within the enclave begins life as an LE pthread and so has the LE ESTAE active for error handling. CICS enabled threads will addi...

Given the Metal C run-time library includes qsort, it should include bsearch

Provide option for open() and fopen() to set the CCSID of a newly created file

Support a new environment variable that would make LE's runtime open() and fopen() functionsset the attribute of a newly created file to a given CCSID. This environment variable could be named something like _EDC_NEW_FILE_CCSID. If set, for exampl...

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...

LE __heaprpt() that doesn't freeze all threads

We use the LE callable service __heaprpt() from C++ but it causes all threads to be frozen. Can we have a version that doesn't freeze threads (i.e from volatile fields in control blocks)? We don't mind if it's closely approximate.
