Concatenating assignment operator - '.='

This concatenating assignment operator - '.=' appends the argument on the right side to the argument on the left side.

Example

  execute ibeblock
  returns(sVal varchar(10))
  as
  begin
    sVal = 'abc';
    sVal .= 'def';
    suspend;
  end       

Now sVal is equal to 'abcdef';

<< ENUM data type | IBEBlock | IBECallFBShutdown environment variable >>
