| Be careful! AS is quite good. It will access flat files, VSAMs and
DB2 files. The real killer is the AS graphics component. AS will
do all sorts of graphics, based on GDDM of course. The graphics
are scalable (sizing is optional), data labels can be moved around
by the user. The graphs are close to high resolution-type graphics.
They are very flexible, and quite simple for end-users to learn.
For applications and reporting, AS is PFkey-driven, and again easy
to use. Equalling AS will require a good end-user application
development/report writer with a very good graphics package.
Call me for suggestions.

| 1) Performance can be quite bad, when not using the SQL interface.
Adding users also rapidly degrades performance. I recall that users
were required to log on with a memory size of 4MB.
2) Access to DB2 databases is not locked as with TEAMDATA. Multiple
concurrent users of the same DB2 data from AS can result in lost
updates.
3) DB2 has a limit of 15 joins. Using a query from AS reduces this
limit to 14.
4) The user interface and general facilities are quite good. It
even includes a word processing facility (much like RUNOFF). Similar
tools are available in the DEC environment, they just aren't integrated
the way they are in AS.
5) IBM sells AS as a 4GL.
