If you want to use white spaces like tabs, new lines, or carriage returns in a string, use the text() macro.

Syntax
aWhitespaceString = text(LITERAL);
Semantics

Transforms all escaped white spaces found in a string literal to a real white space. The text macro takes only string literals as parameter. Returns a new string. Only the following white spaces are supported:

  • \n     new line
  • \r      carriage return
  • \t      tab
SubstitutablesLITERAL String literal. 
Examples

The literal contains the escaped white space \n, which is transformed to a real line break.

set whitespaceString = text("First line.\nSecond line.");
