What about just using sprintf into a string and then cout the string? HTH

Hmmm. Thanks. Link certainly seems relevant. (Interesting -- the page that opens is some weird VM-z/OS hybrid: z/VM z/VM 6.2.0 IBM XL C/C++ for z/VM z/OS: XL C/C++ Programming Guide Coding: Advanced Topics Using decimal data types in C Programming examples.) But I find the same example in the z/OS XLC P/G PDF, so macht nichts. But I consistently get 'D(*,*' for output. Here is my exact format: "%*.*D(*,*)" and I am calling it with 20, 5, &decimal_number, precision, scale. (I started out with 20, 5 like in the example just to make my life easier.) Here's a rub. The code is C++ and fixed point decimal support is limited to C ... but ... at the Spring TDM I asked a guy from Toronto why the heck the fixed point decimal support is only C and not C++. He told me -- very interesting story but I am going to play it safe here and assume it is under NDA. But he did tell me that I could call printf() from C++ and format fixed point decimal with no issues as printf() is a C function, not C++. I had not added decimal.h to my code as there is no packed logic other than the printf() (data comes in from an external source). I added the #include but still no joy. I think I will write to the Toronto guy and ask him the same question I asked here.

KC offers this: <https://www.ibm.com/support/knowledgecenter/SSB27U_6.2.0/com.ibm.zos.r12.cb cpx01/pex1.htm> This page contains the following: printf("pd02 = %*.*D(*,*)\n", 20, 5, digitsof(pd02), precisionof(pd02), pd02); This appears to do what you want, but you will need to specify the width and decimal places for the output field too. -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
