Line continuation

By default, an instruction ends at the end of line.

If a single instruction is written on several lines, then each line, except the last one, must end with a space followed by the line-continuation-character & (ampersand).

Example 16.6. Line continuation

instruction on one line:

foo = bar + tar + zar

same instruction on 3 lines:

foo = bar + &
  tar + &
  zar
