Answer:
We've got a lot of memory leak problems. Yes, I've incorporated lots of the standard stuff to reduce it (appending with buffers etc.).

But I've got a lot of library functions that calculate a string value and return it; whereas the callers routinely dumps it in a buffer:
buffResults += GetAttrVal(obj, NameAttr).

I've not had much luck with functions returning Buffers since doing so creates an alias, and who knows what's happened to the original buffer.

Anyway, I'm looking for a lot of examples of stuff that [1] DO cause memory leak (permanant string in the String Table), and [2] that involve strings but do NOT cause such leak. For example, do the following cause memory leaks?

bufFinalResults += bufTempResults
bufFinalResults += GetBuffedAttrVal(obj, NameAttr) // GetBuffedAttrVal is function of type Buffer
string sNum = iNum "" // convert integer to string
string sNum = iNum " objs" // convert and concatenate integer to a string

Can you get to the string table to investigate it?

Need lots of specific advice on this.
