Hi in a BASIC routine,
i can use the FIELD function to extract a substring from a string based on delimiters and instances

How can i check if a string S1 is a substring of S2 or not? The substring can occur at any part of S1

Thanks,

How about using Index Function??

You can write your own C++ routine to emulate your requirement.

No need to write anything for Server when all kinds of functionality is already built in. As noted, 'Index' is a good answer here and the returned found position of the substring can be treated as a simple true/false Boolean when just checking for existence.

INDEX works, thanks to all !
