IBM i 7.6 Development tools

It is important to understand the difference between
- fully supported
- removed
- available but not supported.
- available but not supported. Menu option removed. (I assume this means
the command is still available)

As in the following at:
https://www.ibm.com/docs/en/i/7.6.0?topic=rdsi5w-commands-from-rational-development-studio-i-5770-wds-option-21-application-development-toolset

Source Entry Utility (SEU) and Programming Development Manager (PDM) along
with the Interactive Source Debugger (ISDB) are the only functions that
remain *fully supported* in IBM Rational Development Studio for i

menu driven screen interfaces continue to be supported:

- Start Programming Development Manager (STRPDM)
- Start Source Entry Utility (STRSEU) Start Interactive Source Debugger
(STRISDB)
- End Interactive Source Debugger (ENDISDB)
