[GAP Forum] a(n) integer

[Lisette Brillemans]

Dear forum,


English is not my home language so I could be wrong. But today while
programming I made a small mistake about which GAP informed me by:

List Assignment: <position> must be a positive integer (not a integer) at 

I wonder if that "not a integer" should not be: "not an integer".
Or does "a" mean here, "not just an" or so.
Again: English is not my home language so I could be wrong.


With regards,


Lisette
