Job object
This function sets the so-called emulation settings in the running job. The settings must be saved explicitly by the external code.
If SourceDir is set to "", the ini settings are used.
SortMode should be set to 0 = FAT order, 1=Name order, or 2=Time order
Pattern should be set to the file name search pattern, usually *.TIF.
For use in the FORMS Scan module only.
Note that Scan emulate mode is for test purposes only.
