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...

Add support for POSIX.1-2001 posix_spawn() and helper functions

Just to avoid any possible confusion, this is not asking for spawn(). The posix_spawn() function and a set of supporting functions provides the user a wrapper around exec/fork and enables them to create child processes with much more control other...

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...

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.

LE's Heap Latch should be FIFO, not LIFO

Serialization via LIFO has the negative effect of leaving the first task in to never obtain the resource when processing is very busy. FIFO allowed everyone the chance to get in and get out with little delays even during a busy time.

Support Posix semaphores

The Posix semaphore mechanism (defined by these APIs: sem_open/sem_close/sem_unlink/sem_trywait/sem_wait/sem_timedwait/sem_post/sem_init/sem_destroy/sem_getvalue) is an alternative to the XSI semaphore mechanism currently implemented in z/OS. Posi...

Convert EBCDIC to ASCII in Z/OS with EDCICONV don't generate carriage return

There's no way to convert a file from EBCDIC to ASCII or Unicode without copy the file to USS With the utility EDCICONV the file generated don't get any carriage return (crlf or lf). This can easily be done under USS. However, we are looking to pe...

Make CEETBCK statement_id parameter optional for performance reasons

In order to populate the statement_id parameter, CEETBCK needs to invoke the debug infrastructure, which can present considerable overhead if CEETBCK is frequently used ie. in non-error contexts. Passing a null pointer (OMITTED in the case of COBO...

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...
