ABAP program lines are wider than the internal table (转载)

错误详细描述： An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_READ_SRC_LINE_TOO_LONG', was
not caught in
procedure "K_KKB_FIELDCAT_MERGE" "(FUNCTION)", nor was it propagated by a
RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
There was an attempt to read program "Z1S01R001" from the database.
The READ REPORT statement allows you to copy a program text into an
internal table. The occupied line length in the program text must not
exceed the width of the internal table.
The internal table "\FUNCTION=K_KKB_FIELDCAT_MERGE\DATA=L_ABAP_SOURCE[]" is 72
characters wide. The program line is 93 characters wide。
今天写个ABAP程序，一运行就荡掉，刚开始也没仔细看出错提示，以为是自己的代码写的问题，最后才搞懂，唉，原来是SAP系统不允许书写的代码长度超过72个字符，我的注释行的字符数太多了，导致了荡掉，唉，把长度很长的代码行，包括注释行，都变成72个字符以内后，就OK啦。
