Regexp not picking up as expected

Thank you pixxxel schubser​!!!

I am still learning the ins and outs of regexp. I appreciate the help and feedback!

I will use your improvement on my for ors statement for sure. I have a similar script that I prompt the user for input and this is way better.

In this particular script I have changed from prompting the user for a yes or no input to allowing them to select if they want to increase the font, make the font red, both, or neither with check boxes. Here is the final script with your fixes included. Thank you again!

#target illustrator-22
var doc = app.activeDocument;
var allText = doc.textFrames;
var allLayers = doc.layers;
var check = 0;
var layerName = "Hypertext"
var newFillColor = new CMYKColor();
newFillColor.black = 0;
newFillColor.cyan = 0;
newFillColor.magenta = 100;
newFillColor.yellow = 100;
// Panel for checkboxes
var userPrefWindow = new Window('dialog', "Select your output options...");
// group the check boxes
var checkBoxGroup = userPrefWindow.add("group");
checkBoxGroup.orientation = "row";
// increase font check box
var changeSize = checkBoxGroup.add('checkbox', undefined, "\u00A0Increase Font", {
    justify: "center"
});
// make red check box
var changeToRed = checkBoxGroup.add('checkbox', undefined, "\u00A0Make Red");
// ok button
var buttons = userPrefWindow.add("group")
buttons.add("button", undefined, "OK", {
    name: "ok"
});
// cancel button
buttons.add("button", undefined, "Cancel", {
    name: "cancel"
});
// display the panel we just setup
userPrefWindow.show();
for (i = 0; i < allLayers.length; i++) {
    //alert(allLayers.name);
    if (allLayers.name == "Hypertext") {
        //alert("Found Hypertext");
        check++;
    }
}
if (check == "0") {
    createAndName();
}
// create Hypertext layer
function createAndName() {
    var myLayer = allLayers.add();
    myLayer.name = layerName;
}
var targetLayer = doc.layers.getByName("Hypertext");
for (var i = allText.length - 1; i >= 0; i--) {
    //for (var i = 0; i < allText.length; i++) {
    var textFieldRange = allText.textRange;
    // regexp of content to look for and content to ignore
    if (allText.contents.match(/_|(STARTER(?!\s))|BLOCK AS|(\W(SW(?![A-Z])))|HOURMETER|G7P|CD700|PM410|RELAY|KEYPAD/g) != null &&
        allText.contents.match(/SEAL_CAP|CBL_|_CABLE|THIS SCHEMATIC|SWEEP|FLOOD|FLD|LAMP|BEACON|(N\.O\.)|(N\.C\.)|(PIN)/g) == null) {
        // if red check box is selected, make it red
        if (changeToRed.value == true) {
            textFieldRange.characterAttributes.fillColor = newFillColor;
        }
        // if increase font size is selected, increase the font
        if (changeSize.value == true) {
            textFieldRange.characterAttributes.size = "14";
            //alert("Preliminary");
        }
        // move the text frame to the Hypertext layer
        allText.move(targetLayer, ElementPlacement.PLACEATEND);
        //thisTextFrame.contents = newString;
    }
}
alert("Anything with an underscore has been moved \rto the Hypertext layer.\rReview and cleanup content accordingly. \rNot all components contain underscores and \rsome will need to be moved manually.");

The word PIN I am going to have to be ok with it excluding. There are too many other items that contain the word PIN that I do need to exclude in most other documents.

Here are examples:

IMPLEMENT SHUTOFF SW (PIN 6 POLE 2)

DATA SW (PIN 4 POLE 2)

I guess if there is a way to check and see if there is a ( before the word PIN that would work. Or if it is followed by a whitespace and a digit?

How would you write the regexp for that?

(\(PIN) - for the ( before the word PIN?

(PIN)\S\D - for the not a whitespace and then not a digit?
