Informix Error -22625: REAL type length must be 4 or 8.

Cause and resolution

REAL type length must be 4 or 8.

This message indicates an IBM Informix ESQL/FORTRAN preprocessor error. A FORTRAN host variable of type REAL must be declared as REAL*4 or REAL*8. Correct the length of the REAL declaration and try again.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-22625 fires when a FORTRAN host variable of type REAL isn't declared REAL*4 or REAL*8 — per the official guidance, those are the only supported lengths.

  1. A REAL host variable declared with a length other than 4 or 8, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Correct the REAL declaration to REAL*4 or REAL*8, per the official guidance.
Examples
An unsupported REAL length
REAL*16 MYVAR
Corrected
REAL*8 MYVAR
Diagnostic Checks
  1. Check the flagged REAL variable's declared length, and correct it to 4 or 8.

  • -22623 — "Data type length must be greater than zero." The general data-type- length error this is a specific case of, for REAL.
  • -22624 — "INTEGER type length must be 2 or 4." The same class of type-length restriction, for INTEGER rather than REAL.

A REAL host variable's declared length wasn't 4 or 8 — correct it.
