I got my THINK Pascal (LSP 2.0) yesterday.  My LSP 1.11 project
compiled almost the first time and ran the first time.  Be sure to keep
LSP 1.11 long enough to save your source files as Text Only so that
THINK Pascal can read them.

The LightsBug debugger is significantly improved because it
can display structured variables with field names (for records) and
enumerated type names, like THINK C.

The problem with faking unsigned integers is that you must turn off
both overflow checking, for arithmetic, and range checking, for assignment
to an integer variable of the illegal value -32768. (With LSP 1.11,
I suspect that building an application ignores compiler
directives because my program ran correctly within LSP but not as an
application until I turned off R and V options for the whole file.  I
dont know whether the same problem exists in the new THINK Pascal.) 
There really ought to be a note about this in the manual.
