Investigate: some messages are printed into temporary DD

[Martin-Zeithaml]

Currently, some error messages are being printed into temporary DD. For example, with error ZWEL0072E, SYSPRINT only contains the error message, while the cause is located in SYS00001.

To improve the user experience, it would be better to have the error message and the cause consolidated in one place.

Example - wrong path

SYSPRINT

ZWESVUSR ERROR ZWEL0072E Launcher Could not load configurations

SYS00001

ZWEL0318E - failed to read '/zowe/zowe.yaml2' - EDC5129I No such file or directory.

Question

What is the JCL/STC equivalent for 2>&1?

Answer

Is 2>&1. 😄 See this article.
