A real world example: Say a user deleted the model family directory from inside the model base directory. The model base gets messed up and the mfTbl must be patched to let it know the family is deleted. Here are the steps:

1. login as samm
2. Start the patch tool:

   MBpatcher 

1. Set up the model base variable

set MBroot /whatif/samm/DPAD_MB

1. Go into that model base

moveto MBroot

1. Look at the model families table

show mfTbl

1. scroll up to find out what the record number for the macro model family you

deleted and keep track of that number

1. Start patching the model family table

patch mfTbl

1. Tell it the record number you found in 6 and it will print the info about

that record

1. Tell it we want to delete this record

creFlag = “F_DELETED”

1. Complete the patch:

done

1. Close MBPatcher

quit
