location.

*** empty log message ***

Added an initial explanatory comment.

Removed comment which inhibited directory removal when done.

Modified to accomodate the test driver and its documentation.

Moved direct invocation logic to end of file. ...

Added a __all__ entry at the end of the file to explicitly name the
public symbols.

Cleaned up the string too short/too long error messages.

Changed VarDescriptor base class to inherent from 'object'. This ...

makes it possible to use the 'super' operation when subclassing from
this base.

Changed the file open logic to only trap on an IO Error. Other errors ...

fall through and cause a Python error exit.  Necessary so that program
errors are not caught and treated like a bad file open.

Implemented the ELSE directive.

Retructured CondStack to prepare the way for ELSE directives.

Inhibited declaration/reference of null-named variable. ...

Inhibited declaration/reference of variables with whitespace in their

existing values' descriptors were being overwritten with a new
descriptor.

Added code to protect Read Only variables from being changed.

Added basic check of symbol table passed to API to confirm a valid ...

variable descriptor object has been passed for each variable.

condition to False.  This was done for semantic consistency with other

Corrected Literal line processing code to detect extra LITERAL and ...

ENDLITERAL statements.
Corrected semantics of Literal line processing
so that these directives are ignored within False conditional blocks.

line.  This was done for consistencey with ENDLITERAL.
