FabSim version 3.0

The format of lot_sequence.strt and lot_single.strt has been changed!

A new column attr: has been inserted between columns prod: and wafers:.

Please check your previously used -in_strt files and add the column if still missing.

The attribute may be freely chosen for each lot and used in the customer
dispatch interface Cdispatch.dll.

Details of this interface are given only with the full version of FabSim. 

A sample Cdispatch.dll accompanies this demo. In the column "dispa" of
mach_dat.mset or on the command line (using -all_dispa nnn) you may select
nnn as 10x or 20x where x is 0...5 (the already available dispatch 
procedures FIFO, CR, SPTF, ODD, EDD, WSPT). 10x will select a priority
sorting according to the lot attributes (see above). 20x selects a dispatch
rule which looks at the buffers following the actual process step. The lot
with the smallest buffer occupancy following the current step is selected. 

If several lots have the same attribute (10x) or buffer preference (20x), the
dispatch rule x (out of 0...5) is applied.

Cdispatch.dll will generate a debug output. It prints all queues of toolset 4
after sorting if a lot is ready to enter a machine either to console.log or to
the screen (runx.log with x 1...3).
