[GAP Forum] ADD_TO_LIST_ENTRIES_PLIST_RANGE

[KnDMcT at aol.com]

I sent the following question to support at gap-system.org yesterday, but  it 
bounced back as undeliverable. Can anyone on the forum mail list help?
 
Is it possible to get a brief description of the GAP function  
ADD_TO_LIST_ENTRIES_PLIST_RANGE which occurs in the FactInt package file  mpqs.gi as:
 
       ADD_TO_LIST_ENTRIES_PLIST_RANGE
(Sieve,[Pos1,Pos1 + qi..Pos1 +  RangeTable[i]],-Weight);
if   Pos2  <> Pos1 
then  ADD_TO_LIST_ENTRIES_PLIST_RANGE
(Sieve,[Pos2,Pos2 + qi..Pos2 + RangeTable[i]],-Weight); fi;
 
I'm trying to decipher this call and have been unable to locate anything in  
the manual or on the GAP web site. I assume that it manipulates the first  
argument which is a list of integers, but can find no documentation. The second  
argument appears to be a list of indices into the first argument, but I have 
no  clue what the third argument is.
 
Thanks,
