Trouble getting object in-links

I have written a function that is supposed to get all in-links and out-links and display them within an HTML file.  I've tried to write the script as similar to what is in the reference manual, but the in-link section isn't working.  And, yes, I did the stupidity test and made sure that some of the objects indeed have in-links.  Here is the code as I have it written:

Buffer getLinks(Object obj) {
    Link oLnk;
    Link iLnk;
    ModName_ targetMod;
    ModName_ sourceMod;
    Buffer links = create;
    Object targetObj = null;
    Object sourceObj = null;
    string modPrefix = "";
    string pathName = "";
    
    //In-Links
    for iLnk in obj<-"*" do {
        infoBox("InLink");
        sourceMod = source iLnk;
        read(fullName(sourceMod), false);
        sourceObj = source(iLnk);
        modPrefix = identifier(sourceObj);
        
        links += modPrefix "<br>\n";
    }
    
    //Out-Links
    for oLnk in obj->"*" do {
        infoBox("Outlink");
        targetMod = target oLnk;
        read(fullName(targetMod), false);
        targetObj = target(oLnk);
        modPrefix = identifier(targetObj);
        
        links += modPrefix "<br>\n";
    }
    return links;
}

When I run this code, I don't get any errors and only get the infoBox for out-links, so it isn't getting into the In-Links loop.  Anyone's help would be greatly appreciated.

From the reference manual regarding "for inlink in object":

"Note: This loop only assigns to inLink incoming link values for which the source object is loaded; unloaded links are not detected. "

Therefore you should use the loop:

for all link references

Syntax

for linkRef in (Object tgtObject) <- (string linkModName) do {
 ... 
}

So, would I put the "for inlink in object" loop inside the for linkRef loop?  Or do I put it after the linkRef loop?

for lRef in oObj<-"*" do {
    infoBox("Link Ref");
    for iLnk in all(oObj<-"*") do {
            infoBox("InLink");
            sourceMod = source iLnk;
            srcMod = read(target iLnk, false);
            sourceObj = source(iLnk);
            modPrefix = identifier(sourceObj);
        }
    }
}

but I'm not getting the LinkRef infoBox.

I'm sorry if these seem like stupid questions, but I haven't worked with links in DXL before.

for lRef in oObj<-"*" do {
    infoBox("Link Ref");
    for iLnk in all(oObj<-"*") do {
            infoBox("InLink");
            sourceMod = source iLnk;
            srcMod = read(target iLnk, false);
            sourceObj = source(iLnk);
            modPrefix = identifier(sourceObj);
        }
    }
}

The structure you want is

for linkRef in object
   get name of source module of linkRef 
   open source module in read only

for link in object (they are all now visible, as all the modules have been opened above)
   do your action
