Error description
Incorrect Output. The compiler may issue messages IGYPG3173-W or IGYPG3174-W, complaining about something similar to "The result of the comparison of operands A and 9999 is known at compile time, based on the attributes of the operands. Unconditional code was generated."

Problem summary
**************************************************************** * USERS AFFECTED: All users of the Enterprise COBOL V6.4 * * compiler who are compiling source programs * * with a group data item that specifies a * * level-88 condition name where the range of * * values includes the largest value that can * * be represented by the associated conditional * * variable. * **************************************************************** * PROBLEM DESCRIPTION: Incorrect Output. The compiler may * * issue messages IGYPG3173-W or * * IGYPG3174-W, complaining about * * something similar to "The result of the * * comparison of operands A and 9999 is * * known at compile time, based on the * * attributes of the operands. * * Unconditional code was generated." * **************************************************************** * RECOMMENDATION: Apply the IBM provided PTF * **************************************************************** The customer source program contained the following group data item definition in the DATA DIVISION. 01 Struktur. 05 Zahl Pic 9(04). 88 Zahl-gross Value 0003 Thru 9999. Then in the PROCEDURE DIVISION. Perform 10 Times Call 'PTSS64B' Using Struktur If Zahl-gross Then Display 'Grosse Zahl.' Else Display 'Kleine Zahl.' End-If DISPLAY '-----------------------' End-Perform This results in the compiler issuing the incorrect message, as follows. ==000017==> IGYPG3173-W The result of the comparison of operands ZAHL and 9999 is known at compile time, based on the attributes of the operands. Unconditional code was generated. What is actually happening internally is that the compiler translates the statement. If Zahl-gross into the generated statement. If Zahl <= 3 and Zahl >= 9999. The second part of this generated statement is what causes the compiler to issue the IGYPG3173-W message. But the compiler should not have issued the message for an internally generated comparison. The compiler user did not code this statement in their source program, nor can they have any impact on it.
Problem conclusion
The compiler has been changed so that it will no longer issue the IGYPG3173-W or IGYPG3174-W messages for internally generated comparisons.
