I write a process where  A, B and C are variable with text.

Then i have : 'text' := A + B + C

Is it possible to insert a code to have a ligne empty between A, B and C, like 

'text' := A + 'new ligne' + B + 'new ligne' + C

Example :

A = hello john, B= How are you, C= can you phone me ?

i get 'text' = hello johnHow are youcan you phone me ?

But i want 

hello john

how are you

can you phone me ?

Thank you for help
