What is the modifier for prxmatch for case-sensitive?

Hello:

I would like to seach 'BDS' upcase in the string, what is the modifier control for prxmatch? I found the 'I' is not working. Thanks.

if prxmatch("m/(?=.*?BDS)/I", &var) > 0 then found=1;

Lower case i?

i stands for case insensitive. remove i if you want to be case specific. so you should be able to search for BDS this way too but you will find all other cases along with it. Please check the pattern you are using if it has not macthed with i

if prxmatch("m/(?=.*?BDS)/I", &var) > 0 then found=1

change it to

if prxmatch("m/(?=.*?BDS)/", &var) > 0 then found=1

Not your question, but do you need the read-ahead?

How does this work for you:

 if prxmatch("m/BDS/", &var) > 0 then found=1;

or even this:

if index(&var,'BDS') then FOUND=1;
