Non-Printable characters

Postby CPANTX » Mon Aug 10, 2009 11:48 am

I am using cobol file handling program that takes input from RUN JCL and puts it in a PS already created(DISP=SHR). Program is running successfully but when I open the PS to see the contents, it shows non-printable characters.

 ****** ***************************** Top of Data ******************************
 ==MSG> -CAUTION- Data contains invalid (non-display) characters. Use command   
 ==MSG>           ===> FIND P'.' to position cursor to these                   
 000001  #                                                                     
 ****** **************************** Bottom of Data ****************************

Line 000001 is the data that I put in the PS.

Why these invalid characters?

Thanks and regards,

Did your test only write one record? Check to make sure you are actually moving data to the output area before writing.

Look at "your data" in hex. . .

The entire output area needs to have valid data (typically a MOVE SPACES to the output file area or working-storage area) before writing the output.

If the output data contains packed-decimal or binary fields, there will usually be non-display characters in the output.
Hope this helps,
