Continuation characters

Use them to continue control statements and comments that do not fit on a single line of input. The continuation character must be the last nonblank character. Use the continuation characters as follows:

• Use the plus sign (with no spaces before it) to continue values for a single keyword to a second line (or subsequent lines). The plus sign deletes leading separators from the continued line.
• Use the minus sign (with a space before it) to continue a list of keywords for a single command. The minus sign does not delete leading separators from the continued line.
