contains()

The strLib.contains() system function determines if a specific sequence of characters is present within a string. Returns “true” if the sequence of characters is found within the string. Otherwise, it returns “false”.

Syntax

  strLib.contains(
             target STRING | CHAR | DBCHAR | MBCHAR | UNICODE In,
             sequence 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.

sequence

Inputcan be any value that is assignment compatible with any of the above types.

result

Returns“true” if the sequence is a substring of the target, “false” if it is not.

Example

  function main()
       myString String    = “Customer”;
       substring String   = “sto”;
       myChar Char(8)     = “Customer”;
       subChar Char(3)    = ”abc”;
       myUni Unicode(8)   = “Customer”;
       subUni Unicode(3)  = “sto”;

       sysLib.writeStdout(“Is ’sto’ contained in ‘Customer’? “ + strLib.contains(myString, substring)); 
       sysLib.writeStdout(“Is ‘abc’ contained in ‘Customer’? “ + strLib.contains(myChar, subchar)); 
       sysLib.writeStdout(“Is ‘sto’ contained in ‘Customer’? “ + strLib.contains(myUni, subUni));
   end

The output is as follows:

‘sto’ is contained in ‘Customer’? true 
‘abc’ is contained in ‘Customer’? false 
‘sto’ is contained in ‘Customer’? true
