Is there any way to programmatically access the single enum and multi-enum'

Is there any way to programmatically access the single enum and multi-enum's "related numbers"?

I'd like to develop a layout DXL that compares the "related numbers" of the object's selected enum values and compare them against another single-select enum's "related value" for the same object, and the result would be to display text such as "Valid" or "Invalid".

Example:
"MasterEnum" is a single select enum (Values=Red/Blue/Yellow/Orange, related values 1/2/3/4 respectively)
"SecondaryEnum" is a multi-select enum (with 15 possible values "A", "B", etc with related numbers 1-15 respectively).

From the specified sample MasterEnum and SecondaryEnum values below, my layout column would hopefully produce the display, for the reason given:

SecondaryEnum - MasterEnum - Display --- (Reason)
A,C

Don't deal with those; but here goes. Maybe this is a hopeless approach and if so someone will correct me.

int    fGetRelatedNumber(Object in_obj, string in_NameAttr)
{     // Get the 'Related Number' of the object attr value,
        //      which must be Single Enumerated.
        // Return -1 when there is some error
 
        if (null in_obj or null in_NameAttr)    return(-1)
 
        string  Value = probeAttr_(in_obj, in_NameAttr)
        if (null Value)                         return(-1)
 
        Module  mod = module(in_obj)
        if (null mod)                           return(-1)
 
        AttrDef ad = find(mod, in_NameAttr)
        if (null ad or ad.multi)                return(-1)
 
        AttrType at = ad.type
        if (null at or at.type!= attrEnumeration) return(-1)
 
        int     i
        for (i=0; i<at.size; i++)
        {  if (at.strings[i] == Value) break
        }
        if (i >= at.size)                    return(-1)
        return(at.values[i])
}     // end fGetRelatedNumber()
 
Object oCurr = current
print (fGetRelatedNumber(oCurr, "CP Attr - Status")) "\n"

You don't have to loop over the possible attribute values:

string s = obj."in_NameAttr"

returns the string attribute value, while

int i = obj."in_NameAttr"

returns the related integer number.

string s = obj."in_NameAttr"

int i = obj."in_NameAttr"

Doh! At least when I step in the dodo, I do it with flags waving and trumpets blaring. I don't see that fact in the manual, but yes it works.

I notice the int version gets a DXL error for multi-enumerated attributes, even when only one is selected. I notice if you surround the int with noError()/lastError(), you always get zero, even when nothing is selected:

int i=-1
noError()
i = obj.NameMultiAttr
lastError()
print i "\n"    // always prints 0

Seems like then the script needs to KNOW its a single enumerated attr.
