I am not sure i am not able to remove last line "empty" of last bank. File is in other post. I can see i find it and the charCode is 13 so it should be remove with splice but...

function ListBankInstruments(current){
	instName=Abank[current].split("\n");[]
	//REMOVE FIRST LINE "BANKNAME"
	instName.shift();
	//REMOVE LINES NOT STARTING WITH DIGIT OR EMPTY
	alert(instName[instName.length-1].charCodeAt(0));
	
	for (var j=instName.length-1;j>=0;j--){
   	ChCode=instName[j].charCodeAt(0);
	if (ChCode<48 || ChCode>57 || ChCode==13 ) { instName.splice(j,1); }
	}
	alert(instName.length);
	instOptionList();
}

Well i think enough to be able to create linked option lists dynamically from a textfile without creating an object. "That require some IQ" contrary  parroting the symbolic shortsyntax in regexp, that as a tool was outdated in early 70's.

Your comments are pitiful at best LoL

If `Abank[current]` contains multiple lines, use this.

  Abank[current].replace(/^[^\d][^\n]*\n|\n[^\d][^\n]*|^[^\d][^\n]*$/g, "");

But if `Abank[current]` contains an extracted line of a multiline string,
then you're doing the filtering at the wrong point.

Well i think it was better solved with string functions JJ.
