Thanks, but I know all of that already and am already aware of
MapServer's online references and am an experienced user. I also know
about the CGI reference that describes how to change map file parameters
via a URL in >5.0 versus <5.0:
http://mapserver.gis.umn.edu/docs/reference/cgi/referencemanual-all-pages
On further investigation, I've discovered that I must specify a map file
parameter as so in an HTTP GET request:
map_scalebar=size+width+height+intervals+value
But alternatively, I must use a different method for specifying these
map file parameters in an HTTP POST request:
map_scalebar_size=width+height
map_scalebar_intervals=value
This requires me to code for two different scenarios. Is MapServer's
intended behavior or is this an oversight/bug?? Thanks!
Cheers,

Subject: [mapserver-users] How to set SCALEBAR size and intervals in
MapServer CGI >5.0?
Dear MapServer Users,
Prior to MapServer 5.0, I could set the map scalebar size and intervals
using CGI variables named "map_scalebar_size" and
"map_scalebar_intervals". After upgrading to 5.2.0, however, these
variables are no longer recognized; I get an error saying
"loadScalebar(): Unknown identifier". Is it true that we can no longer
reference map settings in this fashion? When I change these variables to
"map_scalebar=size+value+intervals+value" it works, but this no longer
fills in my template variables [map_scalebar_size] and
[map_scalebar_intervals]. If I try using a template variable with
[map_scalebar] instead, the value (e.g.
"size+width+height+intervals+value") doesn't seem to be interpreted by
MapServer since the scalebar settings never get subsequently modified.
What am I doing wrong? Thanks for any insights!
Cheers,
