COBCH1612 ACU picture string not supported

You have specified an invalid picture string, for example, a mixture of symbols specified for zero suppression.

This error message is displayed when an invalid symbol (or combination of symbols) has been specified in the picture string when you compile with either the DIALECT"ACU" or the ACU Compiler directive.

For example, in this COBOL system, the combination of numeric and numeric edited symbols in the same picture string must follow strict logical rules:

01 edit-acc-tot1 pic Z9.9Z.	*> this is incorrect
01 edit-acc-tot2 pic 99.ZZ.	*> this is incorrect
01 edit-acc-tot3 pic ZZ.99.	*> this is correct
01 edit-acc-tot4 pic Z9.99.	*> this is correct

You must correct any picture strings that produce this error. For more information on the symbol combinations allowed in this COBOL system, see The Picture Clause.
