The above code set tolerance operand#1 as TTHI.

tolFileName= ‘C:\MYDIR\MYLENS.TOL’;
TheSystem.TDE.SaveToleranceFile (tolFileName);
TheSystem.TDE.SaveToleranceFile('file in default folder.tol');
TheSystem.TDE.LoadToleranceFile ('file in default folder.tol');

• Save tolerance file to user defined path
• Save  tolerance file to default folder
• Leave tolerance file
