Try running this in a DOS version of RBase. I ran it using 6.5+ & 6.5++.
Ran it on a computer running WIN98.
To keep things as simple as possible, I started in the directory where RBASE
is located and copied the CONCOMP DB to this directory.
I wrote 2 simple command files M1 & M2 as follows:
M1 was:
CLS
SEL ALL FROM Sys_Columns WHERE Sys_Column_Name = 'Sys_Query'
SET V vMemStat INT = (ISTAT('MEMORY'))
WRI .vMemStat AT 10 10
------------------
M2 was:
CLS
SEL ALL FROM Product WHERE Model = 'PB3050'
SET V vMemStat INT = (ISTAT('MEMORY'))
WRI .vMemStat AT 10 10
-------------------------------------------
Start RBase with: RBASE65 -R
Get to R>
CONN CONCOMP
RUN M1 (or RUN M2)
(Run this multiple times and watch the results)
My results: The MEMORY value always stayed the same (approx 58,000,000 with
64MB memory)
----------------------------------------
Now try it starting with: RBASE65 -K64 -R (64 is the reported default
value, if no "K" specified)
(remember to CONN CONCOMP)
My results: The MEMORY value decreased 65,536 each time M2 was run and it
decreased 2,424,832 each time M1 was run. The value decreased until it
reached 65,500 and stayed there without any visible effects.
----------------------------------------
Now try starting with: RBASE65 -K1 -R
My results: The MEMORY value decreased 4,096 each time M2 was run and it
decreased 147,456 each time M1 was run. When the value decreased to about
18,000,000 the response time greatly slowed. (Takes a lot of "RUNS" to do
this depending on your installed memory. You could run the programs in a
loop to make it easier to do.)
-----------------------------------------
Now try starting with: RBASE -K1000 -R
My results: The MEMORY value decreased 1,024,000 each time M2 was run and
it decreased 19,456,000 each time M1 was run. After running M2 about 50
times (or running M1 3 times), I was dropped back to the C> with the message
"Insufficient memory to load Protected Mode R:Base"
--------------------------------------------------------------
Any thoughts?
