我想知道，我的代码有什么问题，因为当我编译它时，会出现以下几行中的错误：

hello.cob：在“DADOS”段落中：
hello.cob:25：错误：语法错误，意外“（”，期待 WORD
hello.cob：在“FIM”段落中：
hello.cob:31：错误：语法错误，意外'('

这里是我的程序的来源：

   IDENTIFICATION   DIVISION.
   PROGRAM-ID.      TRIANG.
DATA DIVISION.

WORKING-STORAGE SECTION.
77  BASE    PIC 9(04) VALUE ZEROS.
77  ALTURA PIC 9(04) VALUE ZEROS.
77  HAREA   PIC 9(06) VALUE ZEROS.

SCREEN SECTION.
01  TELA.
02  BLANK SCREEN.
02  LINE 04 COLUMN 21 VALUE

02  LINE 06 COLUMN 15 VALUE

02  LINE 10 COLUMN 21 VALUE "ENTRE COM O VALOR DA ALTURA...".
02  LINE 12 COLUMN 21 VALUE "ENTRE COM O VALOR DA BASE...".
02  LINE 14 COLUMN 21 VALUE "ENTRE COM O VALOR DA AREA...".

PROCEDURE DIVISION.
INICIO.
    DISPLAY TELA.
DADOS.
    ACCEPT(10, 51) ALTURA.
    ACCEPT(12, 51) BASE.
CALCULO.
    MULTIPLY BASE BY ALTURA GIVING HAREA.
    DIVIDE 2 INTO HAREA.
FIM.    
    DISPLAY(14, 51) HAREA.
    DISPLAY(24, 31) "FIM DE PROGRAMA".
    STOP RUN.

谢谢您的帮助。

我将这 2 行放在代码中：

   IDENTIFICATION   DIVISION.
   PROGRAM-ID.      TRIANG.
   DATA DIVISION.

   WORKING-STORAGE SECTION.
   77  BASE    PIC 9(04) VALUE ZEROS.
   77  ALTURA  PIC 9(04) VALUE ZEROS.
   77  HAREA   PIC 9(06) VALUE ZEROS.
   77  ESPERA  PIC 9(01) VALUE ZEROS.

   SCREEN SECTION.
   01  TELA.
   02  BLANK SCREEN.
   02  LINE 04 COLUMN 21 VALUE
   "CALCULO DA AREA DE UM TRIANGULO".
   02  LINE 06 COLUMN 15 VALUE
   "AUTOR: Alexandre".
   02  LINE 10 COLUMN 21 VALUE "ENTRE COM O VALOR DA ALTURA... ".
   02  LINE 12 COLUMN 21 VALUE "ENTRE COM O VALOR DA BASE...   ".
   02  LINE 14 COLUMN 21 VALUE "ENTRE COM O VALOR DA AREA...   ".

   PROCEDURE DIVISION.
   INICIO.
       DISPLAY TELA.
   DADOS.
       ACCEPT ALTURA AT LINE 10 COLUMN 51.
       ACCEPT BASE AT LINE 12 COLUMN 51.
   CALCULO.
       MULTIPLY BASE BY ALTURA GIVING HAREA.
       DIVIDE 2 INTO HAREA.
   FIM.
       DISPLAY HAREA LINE 14 COLUMN 51.
       ACCEPT ESPERA AT LINE 0 COLUMN 0.
       DISPLAY "FIM DE PROGRAMA" LINE 24 COLUMN 31.
       STOP RUN.

添加

77  ESPERA  PIC 9(01) VALUE ZEROS.

和 

ACCEPT ESPERA AT LINE 0 COLUMN 0.

但结果是000000

我得到了程序的工作。几乎。我不知道程序终止时如何保持屏幕亮起，因此结果永远不可见，但至少可以运行程序并输入前两个数字：

       IDENTIFICATION   DIVISION.
       PROGRAM-ID.      TRIANG.
       DATA DIVISION.

       WORKING-STORAGE SECTION.
       77  BASE    PIC 9(04) VALUE ZEROS.
       77  ALTURA PIC 9(04) VALUE ZEROS.
       77  HAREA   PIC 9(06) VALUE ZEROS.
       77  DUMMY  PIC 9(01) VALUE ZEROS.

       SCREEN SECTION.
       01  TELA.
       02  BLANK SCREEN.
       02  LINE 04 COLUMN 21 VALUE
       "CALCULO DA AREA DE UM TRIANGULO".
       02  LINE 06 COLUMN 15 VALUE
       "AUTOR: Alexandre".
       02  LINE 10 COLUMN 21 VALUE "ENTRE COM O VALOR DA ALTURA...".
       02  LINE 12 COLUMN 21 VALUE "ENTRE COM O VALOR DA BASE...".
       02  LINE 14 COLUMN 21 VALUE "ENTRE COM O VALOR DA AREA...".

       PROCEDURE DIVISION.
       INICIO.
           DISPLAY TELA.
       DADOS.
           ACCEPT ALTURA AT LINE 10 COLUMN 51.
           ACCEPT BASE AT LINE 12 COLUMN 51.
       CALCULO.
           MULTIPLY BASE BY ALTURA GIVING HAREA.
           DIVIDE 2 INTO HAREA.
       FIM.
           DISPLAY HAREA LINE 14 COLUMN 51.
           DISPLAY "FIM DE PROGRAMA" LINE 24 COLUMN 31.
           ACCEPT DUMMY AT LINE 1 COLUMN 1.
           STOP RUN.

一个更干净更好的版本：

       IDENTIFICATION   DIVISION.
   PROGRAM-ID.      TRIANG.
   DATA DIVISION.

   WORKING-STORAGE SECTION.
   77  BASE    PIC 9(04) VALUE ZEROS.
   77  ALTURA PIC 9(04) VALUE ZEROS.
   77  HAREA   PIC 9(07) VALUE ZEROS.
   77  AGAIN   PIC X VALUE 'N'.

   SCREEN SECTION.
   01  TELA.
   02  BLANK SCREEN.
   02  LINE 04 COLUMN 21 VALUE
   "CALCULO DA AREA DE UM TRIANGULO".
   02  LINE 06 COLUMN 15 VALUE
   "AUTOR: Alexandre".
   02  LINE 10 COLUMN 21 VALUE "ENTRE COM O VALOR DA ALTURA [____]".
   02  LINE 10 COLUMN 50 PIC ZZZ9 Using ALTURA.
   02  LINE 12 COLUMN 21 VALUE "ENTRE COM O VALOR DA BASE...[____]".
   02  LINE 12 COLUMN 50 PIC ZZZ9 Using BASE.
   02  LINE 14 COLUMN 21 VALUE "            VALOR DA AREA..".
   02  LINE 14 COLUMN 48 PIC ZZZZZZ9 From HAREA.
   02  LINE 16 COLUMN 21 VALUE "                    FINIS...[N]".
   02  LINE 16 COLUMN 50 PIC X Using AGAIN.

   PROCEDURE DIVISION.
   INICIO.
       DISPLAY TELA.
       PERFORM SCREENS UNTIL AGAIN  = 'Y'
       STOP RUN.
   SCREENS.
       ACCEPT TELA.
       MULTIPLY BASE BY ALTURA GIVING HAREA.
       DIVIDE 2 INTO HAREA.
       DISPLAY TELA.

结果是“00000”的原因是您没有验证输入。

就您的程序而言，用户必须为每个值输入四位数字，如果仅输入三位数字，则计算失败。
