[mapserver-users] Run-time Substitution and Raster file problem

[teknocreator]

This is somewhat related to the post by Kathleen Hirst on Feb 27.  We're
using MapServer 6.0.1 and I'm attempting get around the fact that one isn't
able to change the PROCESSING "BANDS=" directive via Run-time Substitution. 
I couldn't find a way to do it through modifying the URL that's passed
either.  As we don't have a many rasters in a file as Kathleen, I thought of
splitting the bigger file up into individual rasters.  Then use Run-time
Substitution and pass in either the filename or just a piece of the file
name to the DATA portion of the mapfile.  The docs seem to indicate I should
be able to do this.  But, I get an error with each attempt.  Here's what I
tried first:

    END
....


  END # End of mosaic layer

END 

But this results in:

"loadLayer(): Unknown identifier. Parsing error near (%):(line 90)
msOutputFormatValidate():"

I tried a few variations:
- using RTS for the entire file name
- specifying the entire path
- quotes/no quotes around the full file path name (different error with
quotes)

to no avail.  I tried others these either ended up in other errors.  Pretty
much hitting walls everywhere and winding up with some of the same
variations.  So, thought it was time to ask what I might be doing wrong or
if this is even possible.  I've used RTS successfully with Postgres/PostGIS,
so I thought this should work as well.  And it's the DATA statement where I
thought this would most likely work.

Appreciate any thoughts/help!
