Use a message subfile to return error information to the user.
Written by Bruce Vining
Anyone who has been following this column for a while probably knows that I believe in using messages whenever possible. Messages are a wonderful way of keeping textual information out of my code, thereby allowing me to reword some text without having to change an application program, a command definition, and so on. One place where I find that many developers (CL and otherwise) are underutilizing messages is in the area of display file error-reporting.
