Debug unicode data

Not able to view the contents of Unicode fields within debug interfaces


Use Case:

When using STRDBG or System Debugger GUI to view the contents of Unicode fields (CCSID 13488) replacement characters are shown rather than the true value of the Unicode field.

    Note that we are we are considering support for Unicode debugging through RDi. This is being tracked with an RDi RFE -- if this would be helpful to you, please vote for the RDi RFE here: https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=122325

    The CAAC has reviewed this requirement and recommends that IBM not implement this request. The function can be done now -- it is already there as Vern indicated below.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

    Answers to questions:
    1. Yes, make the debugger show the contents of a Unicode variable with CCSID 13488
    2. Program language is RPGLE
    3. The contents of the Unicode variable show unprintable characters. Job code character set identifier and default code character set identifier is 37.

    1. The requirement is to make the debugger show the Unicode variable with CCSID 13488 by debugger command EVAL, right?
    2. What programming language does the customer want to enhance by this support?
    3. Can I get a screen capture for the wrong case now? And the job ccsid, job default ccsid when this screen capture did. And the program source code also.
    please issue CL command, dspsysval qccsid, and input 2, and page down 3 times, something like:
    Coded character set identifier . . . . . . . . . : 65535
    Default coded character set identifier . . . . . : 37

    Note also that there are questions below from CAAC and Vern who help to assess RFEs.

    We need answers to these questions in order to proceed with assessing this request. Submitter should answer, but others have also voted for this request -- any of you can add a comment to help clarify the request. Thank you in advance.

    I tried to test this and did not have any problem when using STRDBG. Our machine, at 7.1 of i5/OS, is set to QCCSID 65535 (yes, I know!!!), I have a table defined with columns as follows:

    UNIFIELD CHAR(30) CCSID(1208) value = 'This is a unicode field'
    UNI13488 GRAPHIC(10) CCSID(13488) value = 'is 13488'

    I have a small program to read the table:
    dcl-f UNICODE rename(UNICODE : RLUNICODE);
    read unicode;
    unifield = unifield;
    uni13488 = uni13488;
    *inlr = *on;

    Using STRDBG, cursor on uni13488 and pressing F11, it displays the value clearly.

    There IS a formatting option code one can add to the end of the variable, as in EVAL UNI13488:U - to display CCSID 13488 - it gives the same text, plus a couple reverse-image squares that are not even in the variable, so far as I care to check.

    So I'm curious about just what the environment is where this does not work - I assume that QCCSID is something different from 37 (I'm in the US) and maybe not 65535.

    Is the variable in question set to something other than 13488? I mean, the contents are in that CCSID but it's not tagged for that? Is it a regular character thing? Then try using the :U formatting option code.

    The CAAC has reviewed this RFE. More information is needed. In STRDBG, see if there is a colon plus a character after the variable name that can modify how it's displayed. That would then present it in regular character mode. In the graphical debugger, right click on the variable to see if there is a way to display it other than as unicode. Please add a Comment to this RFE to let us know if these suggestions worked.
