Sat, 15 Mar 2014 20:10:20 +0000 mjsousa Add support for parsing of REF_TO keyword (defined in IEC61131-3 v3). This support is currently inactive (in flex) until we get to add C code generation later on.

Sun, 09 Feb 2014 08:05:44 +0000 mjsousa Fix bug in standard: standard does not allow multiple VAR_GLOBAL ... END_VAR constructs in configurations and resources. This is probably a bug, so we allow it.
Wed, 13 Feb 2013 18:56:25 +0000 Mario de Sousa Add a new node to the abstract symtax tree, which will let us do datatype checking of FB variable declarations using the standard algorithm, and no special cases.
