Here you go... This is my answer. The one with the check performs a ret 
nc before then proceeding to the _findsym. WHatever that means?

Here is the disassembly:
Address - code

_chkfindsym:
    ld l, 44h      ;\
    pop af         ;|-- What does this do?
    ret nc         ;/
_findsym:
    ld hl, (91e1h)
    ld de, (91e3h)
    call 010fh
    ret z
    inc hl
    ld (91e1h), hl
    ret
