The Tcl Mapscript interface should live in the 'mapscript' namespace:

  mapscript::mapObj map1 $file

The file name should include .map

You can examine the 'ms_error' object to get the failure codes:

puts [mapscript::ms_error cget -code]
puts [mapscript::ms_error cget -routine]
puts [mapscript::ms_error cget -message]

The message is rather terse, but you should be able to figure out what
the mapfile parse is complaining about.
