To facilitate the calc is better use spreadsheet for conversion degree into decimal and to calc left,right,top,bottom for scilab to avoid errors .
It is useful for next maps.
Then i save all commands of Brucepos for scilab into file of notepad for made a script and copy and paste into editor of scilab.(i do not know but cannot save the script into scilab)
For other work is only necessary modify only data of left,right,top,bottom into notepad and the file of input.
There is very speedy and safe.
