Informix Error -2934: The format width is less than the allocated display width.

Reasons / Common Causes

-2934 fires when a field's FORMAT string is shorter than the field's width as declared in SCREEN — per the official guidance, the length of the FORMAT string must agree with the length of the field itself.

1. A FORMAT string shorter than the field's declared width in SCREEN, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Review the screen layout, and revise it or the format so that they agree, per the official guidance.

Examples

A FORMAT narrower than its field

SCREEN
{
Price: [price    ]
}
END

ATTRIBUTES
  price = unit_price, FORMAT = "###.##";
-- -2934: FORMAT is 6 characters wide, but the field is 9

Corrected

SCREEN
{
Price: [price ]
}
END

Diagnostic Checks

1. Compare the FORMAT string's character count to the field's width in SCREEN, and narrow the field or lengthen the format so they agree.
