Issue found using the latest version of Dragon Basic under Linux (Commit ID: d2ce042)
Leaving a space between variable name and array index causes unhelpful 'line 1: Unknown token? 1' error. Instead of telling you where the error occurs, it always says 'line 1' instead of the real line number. I believe the original Dragon Basic allowed for spaces (Ignored them), but the new DBC seems to be more strict on this. Might be as-designed, but the unhelpful line numbering is definitely something to look at.
