Hello,
I have encountered a problem running scripts in S+ 2000 on Win NT 4.0.
I have a series of lengthy operations that run on large datasets (I
estimate overall 6+ hours computing time on my PIII 933 MHz). I built an
.ssc file to run them as a sequence of assignment commands, but when I run
it S+ takes up more and more memory until it eventually bombs and nothing
is committed.
Note that this happend using a series of commands in the form:
east.dem.nw.7.0 <<- par.map.nw(get("east.dem", immediate = T),7,0)
(where par.map.nw is a function that call a C DLL)
I also tried
assign("east.dem.nw.7.0", par.map.nw(get("east.dem", immediate =
T),7,0),immediate=T)
or
dbwrite("d:\\_demconic","east.dem.nw.7.0", par.map.nw(get("east.dem",
immediate = T),7,0))
In all cases, following S+ with the NT task manager, I can see that memory
is not freed when each operation is concluded, but only when the .ssc file
finishes running successfully (in the dbwrite case I don't even seem to be
able to find the object with its proper name once it has been written to
the attached database).
Any insight?
Cheers
