--- Start of Idrisi List message
In a totally unrelated question. I wrote a VBA app to import, reclass,
and concatenate multiple (all) SDTS DEMs in a directory. It actually
worked quite well (which surprised me since the last time I programmed
anything was in dbase). However when I ran it on the full set of quads
that I wanted to combine (about 40ish), it blew up. After a lot of debug
sessions, I finally located the problem (I think). The best I can tell,
to use the RunModule function to call CONCAT, I need to create a string
variable with all of the filenames (including paths!), to spit out as
part of the parameters that CONCAT requires; this works fine for a few
files, but it *appears* that RunModule is only passing 255 characters to
CONCAT (or CONCAT is dumping at 255). At first I thought it was VBA
clipping the string, but I had the app display the big string and write
it to a text file, which worked fine (something like 4800 characters I
believe). So the question: is this a known issue, and am I wasting my
time trying to make it work? The next thing I was going to try was
dumping the text as a .iml file, and then calling the CONCAT with that,
but if it's a limitation with CONCAT, I won't bother. Which is not to
say I'm unhappy with Idrisi, I love it! (I think) :) Any ideas are
definitely appreciated.
