I would really appreciate any advice, assistance, sample QUEL code, or INGRES
batch files using the following INGRES features: 1) The 'mark' & 'branch'
capabilities of the terminal monitor. Specifically, why the hell does INGRES
always return the message "Can't branch on a terminal" when the branch and
mark commands are coming from a file read in from UNIX (i.e. with "\i
batchfile") ?  If "\i" isn't sufficient to temporarily redefine STDIN as a
file, what else has to happen ? The documentation, as always, remains silent.
I get the same results when both input and output are redirected from files
(i.e. (ingres dbname < input ) > output. Does anyone have ANY idea how to use
mark & branch ???

2) Syntax for conditional expressions evaluated in a branch statement.

3) Any macro definitions which can be used to verify a string format
(specifically, date format). I've written a series of such definitions and, 
if the documentation is at all accurate, they should work. Alas, they do not.

4) Has anyone else had problems defining integrity constraints ? Our system
crashes on a regular basis with a message about a UNIX error. 

Thank you very much.  Also, would anyone be willing to give their phone number
so that I could call to ask questions?
