extract a particular sting

[#1]

Hi, 

I want to extract the bin values from the rows and store in the list.

For example- 

BIN = "B" 8 "Bad Bump" -> I want to extract letter "B" from the string  and store in the list

BIN = "P" 6153 "PCM"  -> I want to extract letter "P" from the string and store in the list and likewise for all the rows containing bin

Here is what I tried so far. It only extracts the row 13

Names Default To Here( 1 );
Clear Globals();
Clear Log();

dt = current data table();
asa = dt << Get Rows Where (Contains(as column(3), "BIN") & Contains(as column(3), "NULL") == 0);

binlist = {};
startrownumber= asa[1];


for(k =1, k<= Nitems(asa), k++,

Insertinto(binlist, db_test:Bins[asa])
	
	
);
binvaluelist= {};


 for (i = startrownumber, i <= nitems(asa), i++,

	newlist = dt:Bins[i];
	
	word_list = words(newlist, "\!"\!"");
insertinto(binvaluelist, word_list);
	
);

If this is related to text parsing from Import x and y values from the text file to jmp table and create wafer map I would use different approach. But let's assume that we start with the existing data table.

I would most likely use Regex if the pattern stays always the same:

Names Default To Here(1);

dt = Open("$DOWNLOADS/Bin table.jmp");
bins = {};
bin_rgx = "\[(?:BIN = \")(.*)(?:\" \d*)]\";

For Each Row(dt,
	If(Starts With(:Bins, "BIN = "),
		bin_str = Regex(:Bins, bin_rgx, "\1");
		Insert Into(bins, bin_str);
	);
);

show(bins); // bins = {".", "1", "2", "B", "P", "N", "A", "3", "F"};

Thanks Jarmo. It works

I tried on a different wafer and it doesn't work for some bins 

BINS = 4
BIN = "A" 2 "Alignment_Die"
BIN = "C" 28615 "D1QM1804101"
BIN = "D" 23501 "D1QM1804102"
BIN = "F" 0 "Fail" ""
BIN = "N" 0 "Not Tested"
BIN = "P" 2806 "PCM die" ""

 bins = {"A", "C", "D", "F\!" 0 \!"Fail", "N", "P\!" 2806 \!"PCM die"};

dt = current data table();
bins = {};


bin_rgx = "\[(?:BIN = \")(.*)(?:\" \d*)]\";

For Each Row(dt,
	If(Starts With(:Bins, "BIN = "),
		bin_str = Regex(:Bins, bin_rgx, "\1");
		Insert Into(bins, bin_str);
	);
);

show(bins); // bins = {"A", "C", "D", "F\!" 0 \!"Fail", "N", "P\!" 2806 \!"PCM die"};

I would suggest testing out the regex either on JMP or on https://regex101.com/r/DPngn1/1 . Choose one failing string and then test it out to see how and why it fails. In this case my regex pattern does require slight modification as it sometimes matches too much.
