tcl api known problems
-----------------------

(i) different behavior to sh or C api for tet_xres file handling

I discovered some behavor that is different than the sh or C api.
When creating the tet_xres file the TCL api does not remove the old
one. This means if you run with EXEC_IN_PLACE set to true or just
run a test by hand the results are appended to the old tet_xres file.
The C and sh api do not do this.

This fix should be easy. Around line 369 in the tcl.tcm.dat file
the tet_xres file is created. If an rm -f was added here any old
tet_xres files could be removed.


(ii) incr function incorrect

I found another small problem with the tcl api. The incr function in
tcl take an arg without a $ ie:

incr garp
not
incr $garp

This seems a bit odd to me also but thats the way it works. Anyway
the tcl api uses incr both ways. There are about 4 incorrect uses.

FIX:

edit all the files and search for incr and delete any $


(iii) tet_reason does not work

Problem:
tet_reason does not work

Fix:
change line 155 in tetapi.tcl from:
puts[lindex 1 $line]
to:
puts[lindex $line 1]
