以下是STRING动词的一个工作示例,它可以满足您的需求:

   IDENTIFICATION DIVISION.
   PROGRAM-ID. EXAMPLE.
   DATA DIVISION.
   WORKING-STORAGE SECTION.
   01    WS-S1 PIC X(10) VALUE 'HI '.
   01    WS-S2 PIC X(10) VALUE 'HOW '.
   01    WS-S3 PIC X(10) VALUE 'ARE '.
   01    WS-S4 PIC X(10) VALUE 'YOU?'.
   01    WS-CONCAT PIC X(43) VALUE SPACES.
   PROCEDURE DIVISION.
   MAIN-PARAGRAPH.
        STRING WS-S1 DELIMITED BY SPACE
               ' '   DELIMITED BY SIZE
               WS-S2 DELIMITED BY SPACE
               ' '   DELIMITED BY SIZE
               WS-S3 DELIMITED BY SPACE
               ' '   DELIMITED BY SIZE
               WS-S4 DELIMITED BY SPACE
          INTO WS-CONCAT
        END-STRING
        DISPLAY '>' WS-CONCAT '<'
        GOBACK
        .

输出是:

>HI HOW ARE YOU?                            <
