RE: Wrapping API in service program

["Smith, Nelson" <NSmith@xxxxxxxxxxx>]

We do exactly that, Buck, and then list all the service programs in a single
binding directory, and add that binding directory to our create command
defaults, so that programmers don't even have to think about it.  All
procedures are then available to all programs.

We also put all the prototypes in a single source member and use the "IF
Defined" compiler directive so that only requested prototypes are copied
into the actual programs that need to use them.  The prototypes source
member itself, then becomes the universal list of all publicly-available
procedures.

With this scenario, programmers who only want to "use" procedures don't need
to concern themselves with the nitty-gritty details of how they are
implemented.  All they have to do is select a procedure from the prototype
list, include the prototype's copy member in their program, and use it.

What we don't have that I would like to see is some sort of nice cataloging
utility.  Something that presented the procedures graphically in a
tree-chart, by function, would be wonderful.  Does anyone have anything like
that?
