Ask the Wizard Questions


The Question is:

Terminal driver doesn't seem to interpret correctly the
COBOL display sentence (e.g. Display "This is data").
Instead of displaying data in the next line, data is
displayed in line 1 column 1.

Do you have any hints.

The Answer is:

    This difference between the DEC COBOL RTL and the VAX COBOL RTL
    is documented in the DEC COBOL User Manual appendix on compatibility:

    If your application uses the Digital extensions to the ACCEPT or
    DISPLAY statements, DEC COBOL positions the cursor in the upper left
    corner of the screen prior to the execution of the first ACCEPT or
    DISPLAY statement.

    This difference is clearly shown when the first ACCEPT or DISPLAY
    statement does not contain the LINE and COLUMN clauses.  In this case
    DEC COBOL moves the cursor to the top of the screen to perform the
    ACCEPT or DISPLAY, whereas VAX COBOL does not move the cursor.
