Placing the Cells
The program, arraygen.exe, generates the MEBES job deck. The header of the job file is read from an external ascii file. The only part of the job deck that varies based on the input parameters are the CHIP and ROW statements which are used to reference the desired cell file and to place it.

As mentioned previously, each cell name includes the information of where it is located in the array. The purpose of the arraygen.exe program is to properly calculate the insertion points for each cell and to format that in the job deck.
