From the Easytrieve 6.4 application guide, p 1-13:
A statement is terminated by a period or the last nonblank character in the statement area, unless that character is a hyphen (-) or a plus (+). The hyphen indicates that the statement continues with the first position in the next statement area (which can be a blank).
The plus symbol indicates that the statement continues with the first nonblank character in the next statement area (which could be in the first position); leading blanks are ignored. For example, the LINE statement, which indicates the contents of a report, is as follows:
LINE EMPLOYEE# NAME STREET CITY STATE ZIP TELEPHONE + REGION DIVISION BRANCH GROSS NET DEDUCTIONS + QUARTER YEAR-TO-DATE
