When I did the demo problem(course 3, demo-p302d04), I am confused about the comprehension about the PRXMATCH function. I know the prxmatch is to search the first position of the character. But I cannot make sense the output table responding to the code created. Can you please help me to learn how to comprehend the result following? Thanks so much!</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Jianan_luna_0-1597782687399.png" style="width: 400px;"><img src="https://communities.sas.com/t5/image/serverpage/image-id/48396iED25F73E2801F265/image-size/medium?v=v2&amp;px=400" role="button" title="Jianan_luna_0-1597782687399.png" alt="Jianan_luna_0-1597782687399.png" /></span></P> <P>&nbsp;</P> <P>&nbsp;</P> <PRE><CODE class=" language-sas"> Loc=prxmatch('/([2-9]\d\d)-([2-9]\d\d)-(\d{4})/',Phone);</CODE></PRE> <P>&nbsp;</P> Tue, 18 Aug 2020 20:31:35 GMT https://communities.sas.com/t5/SAS-Programming/About-PRXMATCH/m-p/677636#M204434 Jianan_luna 2020-08-18T20:31:35Z https://communities.sas.com/t5/SAS-Programming/About-PRXMATCH/m-p/677671#M204437 <P>PRXMATCH returns the beginning position of a substring that matches your <EM>regular expression</EM>.
