How to read .enf file

I have an .enf file which I would like to load into matlab and search for a variable. I have converted the enf file to a .txt in order to upload here, assistance reading this file would be greatly appreciated. More specifically, I would like to know what FP1, FP2, FP3 and FP4 equal, the rest of the file is of no importance.

Currently, I have used uiopen which opens the .enf file into a tab in matlab but I am unsure as to how I use it from here.

A little exercise with regular expression

>> cssm( 'BFND_W6.txt' )
ans = 
  struct with fields:

    FP1: 'Invalid'
    FP2: 'Invalid'
    FP3: 'Right'
    FP4: 'Left'

where

function  sas = cssm( ffs )
%%
    xpr = ['^FP1\x20*=\x20*(?<FP1>\S+).*' ...  
          ,'^FP2\x20*=\x20*(?<FP2>\S+).*' ...
          ,'^FP3\x20*=\x20*(?<FP3>\S+).*' ...
          ,'^FP4\x20*=\x20*(?<FP4>\S+)'   ];
      
    sas = regexp( chr, xpr, 'names', 'lineanchors'); 
end

Comments:

1. the "rows" of xpr must appear in the same order as the rows in the data file, i.e. FP1,FP2,FP3,FP4
2. \x20 is a way to indicate space without using space (it's hex).
3. Space around = isn't needed for this sample file, but just in case.
4. The first FPn in a "row" is the name in the text file, the next FPn is the name of the resulting structure field.
