I have some code in a mac routine that use indentation and the "." character : 
 
 IF condition1 DO
     .WRITE YCR,...
     .WRITE YCR,...
     .WRITE YCR,...I would like to add a try / catch block between the write statements.
I can't refactor the whole code and use indentation with curly braces instead (there is too much code, not written by me)
I have tried the following but it does not work (it compiles, but code stop running right before the try keyword)
