[news.eclipse.technology.dltk] DLTK command name is substitution

[binoctex@xxxxxxxxx (binoctex )]

I am getting a lot of alert messages stating that "command name is 
substitution".  I have googled this phrase and return Zero results.  

basically my TCL code does something like:

if {[info exists Var]} {unset Var}

The [info exists Var] is getting underlined in yellow and reporting the 
command name is substitution text.  I currently have 1,276 alerts and 
would like to clean this up.  If this is configurable from 

If anyone has information on where to read up on DLTK for tcl please let 
me know or provide links of where to start looking.  I cant even find the 
'manual' to RTFM!  I have lots of questions so all references are much 
appreciated.  

I've got my console working (with 4 different interpreters), some basic 
debugging, templates, man pages, and custom libraries.

Im running Eclipse 3.5, DLTK 1.0 on 3 machines - XP, XP 64, and Vista.
