Informix Error -4100

-4100 Illegal definition of constant identifier "name".

A name already established as that of a constant identifier has appeared as a declaration for a new identifier. Suppose, for example, that maxval has already been declared to be a constant in class x, and then a later declaration of VARIABLE x::maxval INT occurs.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4100 fires when a name already established as a constant identifier is redeclared as a different kind of identifier — per the official guidance, for example, if maxval is already a constant in class x, a later VARIABLE x::maxval INT declaration conflicts with it.

A name already declared CONSTANT being redeclared as a variable (or other kind), per the official guidance — the direct, only cause.

Solutions / Resolution

Remove the conflicting redeclaration, or rename one of the two identifiers.

Examples

Redeclaring a constant as a variable

CLASS x
  CONSTANT maxval = 100
END CLASS
...
VARIABLE x::maxval INT
-- -4100: maxval is already a constant in class x

Corrected

CLASS x
  CONSTANT maxval = 100
END CLASS

Diagnostic Checks

Check whether the identifier is already declared as a constant elsewhere, and remove or rename the conflicting redeclaration.
