Detect if Object Text changed since reference date?

Given a reference date (e.g. May 1, 2018), I want to identify all requirements changed since that date, BUT ONLY IF THE OBJECT TEXT HAS CHANGED.

The attached code snippet seems to work, but since the history type constants aren't defined I am guessing somewhat (originally I just checked if h.attrName="Object Text", but that gave errors for some history types).

Does this seem an OK approach?

Date refDate="20 Apr 2018"
Module m=current; if (null m) halt
Object o
History h
Date dLMO
for o in m do
{
        if (isDeleted(o) || o."IE Object Type"""!="Requirement") continue
        if ((dLMO=o."Last Modified On") < refDate) continue
        for h in o do
        {
                if (h.type!=createObject && h.type!=unDeleteObject && 
                    h.type!=modifyObject && h.type!=insertOLE && 
                    h.type!=removeOLE && h.type!=changeOLE && 
                    h.type!=pasteOLE && h.type!=cutOLE)
                {
                        continue
                }
                if (h.type!=createObject && h.type!=unDeleteObject)
                {
                        if (h.attrName!="Object Text") continue
                }
                if (h.date<refDate) continue
                print o."Absolute Number" ", "
        }
}

"modifyObject" history type should also accept the attribute name check - see for example https://www.ibm.com/developerworks/community/forums/html/topic?id=1e2bfc8e-b8d6-4bca-b89b-83fb091c13f5

Thanks ... I had actually seen that thread but failed to look close enough since it was about DXL attribute, my mistake.

I think that will help!
