hello everyone out there,thank you for your attention: (1) #set($a=1) ## I want to output $a+1 which is 2 DIRECTLY,how? If no way ,I can use #set($a=$a+1) or #set($b=$a+1) instead,which is a little complicated. (2) #set($newline="hello\n") ## I want to include a new line charactor in a string varible,when output ,result in a new line,how?
thank you.
