Hello,Yutaka Sung, Thanks for your quick reply.
I made an incorrect description. My second question is: in the Replacement Expression
\J "\0".substr( 0, 5 )
Besides .substr() in the \J expression, if possible to use other Functions.For example:
\J "\0".Left( 0, 5 )
\J "\0".Right( 0, 5 )
\J "\0".Upper( ).......In the help system, only .substr is mentioned.
