Print LE conforming assembler Stack frame storage in CEEDUMP

First I am not sure why LE Stack frame storage is considered language dependent and requires the language to format and print for CEEDUMP. Maybe it is assumed that there will be symbolic data available to match the fields with labels. The LE entry...

LE should give an error for an attempt to start a new enclave in a single-enclave environment

An LE environment that is set up for a single enclave only will not support an attempt to start a second enclave. Currently, if this is attempted in COBOL, the result is a S0C1 in CEEBPIRA. An APAR is open that will change this to be a U4093-92 ab...

Allow disposition to be specified on fopen

DISP=SHR cannot be set when fopening a file in write mode. In read mode it defaults to DISP=SHR. If the file is a PDS(E) member, this locks out the whole PDS(E) so that no-one can browse the other members. If you use a DD Card, then you can specif...

The clock() function that determines process time on z/OS needs to be increased or reset to zero after it reaches max value

We have a PMR 29022,082,000 opened with IBM Integration Bus V10 support about SMF CPU time not reporting correctly for some message flows. L3 found that the clock () function they were using to calculate processor time hit max value so they could ...
