RTL\INC\GenStr.inc file function StrComp: ``` While str1[counter] = str2[counter] do Begin if (str2[counter] = #0) or (str1[counter] = #0) then ``` no need to compare both symbols with #0 coz they are equ. same for StrIComp function. _almost_ the same is for StrLComp / StrLIComp but they are uses "repeat" cycle for now.
