Well, yes and no. Unfortunately that message is no longer being sent. 
There's a bug report in the system to try to get it back, but it's been 
languishing from lack of attention for quite some time.

The difference in the error texts you're seeing is just the IDE's script 
editor interpreting the rather cryptic numeric messages you're seeing 
when you look at the raw data. The lines are of the form

errorNumber, lineNumber, charNumber

and the errorNumber is an index into a list of strings stored in a 
couple of global properties. There's one list for compilation errors and 
one list for runtime errors. I wrote a handy function for PowerDebug to 
show these things because it's awkward trying to remember what the 
various error numbers mean.

function ExplainError pErrorNum, pErrorType
     local tFunc
     local tResult

     if pErrorType is empty then
         put "runtime" into pErrorType
     end if

     switch pErrorType
         case "compilation"
            put line pErrorNum of the scriptparsingerrors into tResult
             break
         case "runtime"
         default
            put line pErrorNum of the scriptexecutionerrors into tResult
     end switch
     return tResult
end ExplainError

...So the error list you see represents

Expression: bad factor
param: bad expression
Commands: bad parameter
Commands: bad parameters
repeat: error in command
Handler: error in command
Handler: error in handler

and normally it's safe to ignore everything except the first line you 
receive.
