Informix Error -4342

-4342 PAGENO and LINENO are allowed only in reports.

These functions are only relevant in the body of a report function (one following a REPORT statement). Only within the report-generating code is the idea of a current page or line meaningful. You can make these values available outside a report through global variables. For example, you could put a statement such as this one in the PAGE HEADER control block:

LET CURR_PAGE = PAGENO

This would assign the current page to a global variable (called CURR_PAGE in the example) that could be tested by code outside the report function.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4342 fires when PAGENO/LINENO is used outside a report function's body — per the official guidance, only within report-generating code is the idea of a current page or line meaningful.

PAGENO/LINENO used outside a report function, per the official guidance — the direct, only cause.

Solutions / Resolution

Make the value available outside the report via a global variable, per the official guidance — for example, LET CURR_PAGE = PAGENO inside a PAGE HEADER control block, then read CURR_PAGE from code outside the report.

Examples

Using PAGENO outside a report

DISPLAY "Current page: ", PAGENO
-- -4342: PAGENO is only meaningful inside a report

Corrected

REPORT myreport()
  ...
  OUTPUT
    PAGE HEADER
      LET CURR_PAGE = PAGENO
END REPORT
...
DISPLAY "Current page: ", CURR_PAGE

Diagnostic Checks

Check whether PAGENO/LINENO is used inside a report function, and if the value is needed elsewhere, capture it into a global variable from within the report first.
