If you have used z/OS for any length of time, then you know that there are many tasks that must be accomplished using the z/OS environment (batch, TSO, or ISPF). Fortunately, the vast majority of those can be simplified using an ISPF dialog, and writing an ISPF dialog is very easy once you've learned a few simple techniques.
To help check out this open-source project located at https://github.com/lbdyck/ispftips or in file 990 on https://cbttape.org. This project includes sample code that you can "borrow" along with documentation in docx, epub, and pdf formats.
The project also includes a simple-to-use ISPF dialog that you can use to experiment with the sample code.
