Using SAS prxmatch to create variable
I would like to create new columns variable using criteria matched in prxmatch.
The first variable 'NEW' is Y if:
a. (A= "YES", B="NO" and C="PRESENT") or
b. (B="NO" and C="MAYBE") or
c. (B="NO" and C in ("NO/FL", "T2/FL "))
else N
The second variable 'NEXT' is Y if:
A = 'NO' and B = 'NO' and E = 'Y'
else N
and the last variable NEWER is Y if
A = 'NEW'
Below is my code but I can't get prxmatch() to work
DATA TEST;
SET TEST.TEST;
if A = 'NO' and B = 'YES' and C = 'PRESENT' then NEW = 'Y';
else if B = 'NO' and C = 'MAYBE' then NEW = 'Y';
else if prxmatch('m/NO/FL|T2/FL/oi', C) > 0 and B = 'NO' then NEW = 'Y';
else NEW = 'N';
if A = 'NO' and B = 'NO' and E = 'Y' then NEXT = 'Y';
else NEXT = 'N';
if A = 'NEW' then NEWER = 'Y';
RUN;
PROC PRINT DATA = TEST;
RUN;

You need to provide some sample data, so that someone can help you to understand why it is not working

Is the information in the first code block actually textual data representing logic rules that need to be evaluated against the data ?

the code for prxmatch did not wotk becacuse you have / and / is used for start and end of regular expression and whenever you have NO/FL it error's out because it your regular expression feels that it came to end and when it few more words after / it fails, so you need to NO/FL as NO /FL, without space as shown in below code.
data have;
input A $ B $ C $;
datalines;
NO YES PRESENT
NO NO MAYBE
NO NO NO/FL
YES NO T2/FL
;
DATA TEST;
SET have;
if A = 'NO' and B = 'YES' and C = 'PRESENT' then NEW = 'Y';
else if B = 'NO' and C = 'MAYBE' then NEW = 'Y';
else if prxmatch('m/NO/FL|T2/FL/oi', C) > 0 and B = 'NO' then NEW = 'Y';
else NEW = 'N';
RUN;
/* i would try something like below just for testing purpose to see how your code
works*/
DATA TEST;
SET have;
if A = 'NO' and B = 'YES' and C = 'PRESENT' then NEW = 'Yah';
else if B = 'NO' and C = 'MAYBE' then NEW = 'Yoh';
else if prxmatch('m/NO/FL|T2/FL/oi', C) > 0 and B = 'NO' then NEW = 'Yay';
else NEW = 'N';
