You should have discovered that PF11 points to the section RELATED. It means that there is a section in the HELP file that contains information about commands related to the one you are viewing. The HELP for rename does not have that RELATED section.
It is true that if you compare the HELP of CMS with the one provided on OS/2 (or other PC software), there is a long way to go (VM is still limited by the 3270 technology). The RELATED sections can be compared to the hyperlinks as we see them on the PC HELP tools. Version 1, Release 2.2 of VM/ESA, enhanced many help files with RELATED sections (especially for CMS Pipelines). Compared to the PC world, we still prefer the CMS HELP for its completeness.
We repeat that if you want to write your own HELP files, you can find the complete documentation in the CMS User's Guide (SC24-5460). You can also XEDIT an existing HELP file to learn from it.
