Understanding How Configuration Works

TBD (this document is being written)

In the 4GL, the ways you can configure a session are inconsistent. To some degree it depends on the type of session (e.g. batch/interactive UI processes vs appserver/pasoe vs classic webspeed). Over time we have built partial solutions for this inconsistent approach which means it is even more inconsistent in FWD. On the other hand, we have a favored approach (using the directory) which is better than any of the 4GL approaches, in my opinion.

4GL Configuration Mechanism Purpose FWD Equivalents
4GL code uses things like built-in functions or system handles (e.g. SESSION:<some_attribute>)
environment variable
explicit command line parameter
.pf file
.ini file
Windows registry
COMPILE options
