I am trying to compare some data between two files.
First I open a file (brd_sym_pn.txt) with data extracted from a database and pull the reference designator($RefDes), part number ($Pnum) and package type ($Pkg_Type).
Then I open another file (sym_text_latest.txt) and extract/assign the part number ($LogPnum) and package type ($LogPkg_Type).
I am trying to compare the $Pnum and $Pkg_Type for each $ RefDes between brd_sym_pn.txt and sym_text_latest.txt, reporting back if the $Pnum/ $pkg_Type does/does notmatches the $LogPnum/$LogPkg_Type assignment in sym_text_latest.txt.
It seems that I have too many loops and should be cycling through each reference designator or line of brd_sym_pn.txt.
I have tried to make this work for about 3-4 days and desperately need some help.
