HOW TO WRITE MULTI LINE IF CONDITION IN SCRIPT EDITIOR

Hi

I have a IF condition like this.

/: IF bwart = '301' and bwart = '303' and bwart = '304' and bwart = '305' and bwart = '306'

• ----

• ----

/: endif

Like this , I have many AND conditions in the IF.

But , In Script Editor , It is allowing only 72 characters.

I extended this SHIFT-F8 to get more characters.

Even, My IF condition is not fitting in one line.

How to write this IF in Script

Thanks
