prxmatch - syntax

Suzy_Cat — Thu, 24 Oct 2019 03:36:26 GMT

hi there, can anyone explain in details each component in below codes? I have tried google but no luck to find info that would help me to fully understand the use of prxmatch:

if prxmatch('m/^[A-z0-9]\.{4}/', code) then do;

{4}

Thanks 🙂

m : operation is matching (optional prefix, almost never used)

/ : pattern delimiter, pattern continues until that character is met again

\ : escapes the special meaning of the period character that follows

. : when escaped, matches a period

{4} : match the previous pattern (a period) exactly 4 times

Thanks 🙂
