Informix Error -4664

-4664 CCL class declarations are required with the "-useccl" switch. Add

To compile a REPORT or the MAIN program block with the -useccl switch, the user needs to include ixstmt.4gh.

This statement has calls to functions nested within the parameter lists of other function calls, to a level exceeding four. A maximum level of four is supported, as in the following expression: Afun(2-Bfun(3+Cfun(4*Dfun(5))))

Rewrite the expression to store the result of the innermost function calls in a variable, and use the variable in the expression.
