Informix Error -1135

-1135 The row or column number in DISPLAY AT exceeds the limits of your

terminal.

Review the DISPLAY...AT statement. Make sure that the position numbers are in the correct order (row number first, then column) and that they make sense for the current terminal or window. The dimensions of the terminal for UNIX systems are determined when the program starts by reading termcap information (or terminfo information, depending on the value of the INFORMIXTERM environment variable). A screen location that is correct for one user of the program might not be correct for all. On DOS systems, the window size is always 24 lines by 80 characters.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-1135 fires when a DISPLAY ... AT statement's row or column position falls outside the current terminal's actual dimensions — per the official guidance, on UNIX these dimensions come from termcap/terminfo at program startup (via INFORMIXTERM), while DOS defaults to 24 lines by 80 columns.

  1. A row/column value in DISPLAY ... AT larger than the terminal's actual size, per the official guidance — the direct, only cause.
  2. The row and column arguments given in the wrong order, per the official guidance's own reminder — DISPLAY ... AT takes row first, then column.
  3. A terminal genuinely smaller than the value assumed by the program, if the program was written assuming a larger standard terminal size.
Solutions / Resolution
  1. Review the DISPLAY ... AT statement, per the official guidance, confirming row is given before column, and that both values are appropriate for the current terminal.
  2. Check the actual terminal dimensions in effect — via termcap/terminfo (UNIX) or the DOS 24x80 default — before assuming a specific size in the statement.
Examples
Row/column reversed or out of bounds
DISPLAY "Status" AT 80, 24
-- -1135: arguments reversed (column, row given as row, column) and/or
-- out of bounds for a 24x80 terminal
Corrected
DISPLAY "Status" AT 24, 1
Diagnostic Checks
  1. Confirm row is given before column in every DISPLAY ... AT statement.
  2. Check the terminal's actual dimensions against the values used.

A DISPLAY ... AT position falls outside the terminal's actual size — check row-then-column argument order and the terminal's real dimensions.
