search substring from vareity of string

[#1]

I have a column with name of failure, which contains all variety of strings. I like to search error code with start of "ex". the error code is 10-character string with start of "ex". and put the 1st error code into column of "1st code", all error codes into column of "all codes. what formula is set to both columns? sorry to bother again. I need to quickly make my work in hands closed firstly, then take time to learn JMP help document.

Here is one way to create these 2 columns

Formula for :fst code

start = contains(:Failure,"0x");
if(start>0,substr(:Failure,start,start+10),"");

Formula for :All Codes

theCodes = {};;
theString = :Failure;
While( Contains( theString, "0x" ) > 0,
	start = Contains( theString, "0x" );
	Insert Into( theCodes, Substr( theString, start, start + 10 ) );
	theString = Substr( theString, start + 10 );
);
concat items(theCodes, ",");
