Description Maarten Becker CLA 2010-08-08 11:56:05 EDT 
Build Identifier: 20100617-1415

The error appears if there is no blank between print statemtent and the format:

Example:
print'(a)',' Hello'

Error: Unexpected character constant ...


But print* (without blank) is working

Reproducible: Always
Comment 1 Jeffrey Overbey CLA 2011-03-17 12:44:28 EDT 
Thanks for the bug report.

Internally, the problem seems to be that the lexer is matching the rule
    {Ident}?"'"
which is intended to match string literals with a kind, e.g.,
    ascii_'This is a string'

I don't see an immediate/easy way to fix this, but I'm keeping this open so we can come back to it later...
