# Pattern matching of character variable

My dataset having character variable as "PANCARD" having total 10 characters and i want to extract a data from 10 thousand records using pattern matching.
Conditions are:-
1) first 5 characters should be alphabets
2) then 4 charcters should be numeric
3) last one is alphabet.
For example.. DHPLO9635G

You didn't say what you want to do once you found a record that matched the condition. The following will find the matching records:

data have;
input pancard \$10. x y;
if prxmatch("m/[A-Z]{5}\d{4}[A-Z]/oi",pancard) > 0 then found=1;
else found=0;
cards;
DHPLO9635G 1 1
DH1LO9635G 0 0
;

@art297 can we do the same without using PRXMATCH function?

## Re: Pattern matching of character variable

There's often more than one possible solution to solve a given problem with SAS. In this case you could use something like:

```data have;
input pancard \$10. x y;
if (countc(substr(pancard,1,5),,'ai')+
countc(substr(pancard,6,4),,'d')+
countc(substr(pancard,10,1),,'ai')) eq 10 then found=1;
else found=0;
cards;
DHPLO9635G 1 1
DH1LO9635G 0 0
;
```
