Re: display not outputting correct number of characters

Since you did you not use the Code button when posting your program and data, it is not possible to determine what happened. There could be a space before the D, for example -- as posted, spacing is not preserved so we cdannot rule that out.

What platform are you running this program on?

ideaone is a website with various "online" compilers and processors. The Cobol on the site is OpenCobol or TinyCobol.

I can't see anything wrong with the program, and enrico has run it.

It is either something with whichever compiler you chose to use, or with how you entered the data on the site.

You could download OpenCobol for yourself, and try it independently of the site. Depending on results, take it up with OpenCobol (at SourceForge) or ideone or with TinyCobol.

since I was curious,
my program as written does not compile on ideone.

getting
Error: syntax error, unexpected WORD, expecting '.'


I am just curious, and I do not speak COBOLESE
so my program could be just wrong in other ways ;)
cheers

PROGRAM-ID needs a period after it before the program name. This is not an error in Enterprise COBOL, but ideaone thinks it is.

Just for fun...
Change WS-TYPE from PIC X(02) to PIC X(03)
and see if the period gets displayed [I think it will ]

but..thats not how it is supposed to be
A big problem for beginning programmers is that they "know" what the results should be as opposed to what actually occurred. No matter what compiler you use, there should be a manual available for it. That manual will tell you what the results will be for any given expression in the language. You may think the result you got is not how it is supposed to be, but it is entirely likely that the results you got are what to expect from that compiler. As previously indicated, the results you got are NOT the results you would get by using the IBM Enterprise COBOL compiler on a mainframe, but there are differences between compilers. Using words like "supposed" or "should" are red flags and indicate you are projecting your desires onto the computer rather than accepting the results you got.
