isMatch()

The strLib.isMatch()system function checks if the string matches a given regular expression. It returns “true” if the string matches the entire regular expression, “false” otherwise.

Syntax

   strLib.isMatch(
             target STRING | CHAR | DBCHAR | MBCHAR | UNICODE In, 
              regex STRING | CHAR | DBCHAR | MBCHAR | UNICODE In)
  returns (result BOOLEAN)

target: Input can be any value that is assignment compatible with any of the above types.
regex: Input can be any value that is assignment compatible with any of the above types.
result: It returns “true” if the regexmatches the targetstring, “false” otherwise.

Example

  function main()
          myStr String = “Customer”; 
          regexStr String = “(.*)sto(.*)”; 
          myChar Char(8) = “Customer”; 
          regexChar Char(11) = “(.*)sto(.*)”;

          sysLib.writeStdout(“Does ‘myString’ match the regex? “+ strLib.isMatch(myStr, regexStr)); 
          sysLib.writeStdout(“Does ‘myChar’ match the regex? “+ strLib.isMatch(myChar, regexChar));
  end

The output is as follows:

   Does myString match the regex? true 
   Does myChar match the regex? true
