It took a little doing, since it had to be moved on tape 
from an isolated box, but here are the relevant excerpts:

This version of the conversion descriptor open kept 
consistently returning -1 in cd.
cd = 
iconv_open("IBMCCSID008500000000\0\0\0\0\0\0\0\0\0\0\0\0",
    "IBMCCSID00037\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0");

It also did so with parameters of "IBM-850" and "IBM-037" 
copied out of the example in the C++ reference, and as 
above, but with the "conversion alternative" in the "from" 
parameter set to 057.



This version of the initialization at least opened a 
conversion descriptor.
QtqCode_T asciiCode;
QtqCode_T ebcdicCode;
           .
           .
           .
        memset(&asciiCode, 0, 32);
        memset(&ebcdicCode, 0, 32);
        asciiCode.CCSID = 819;
        ebcdicCode.CCSID = 37;
        cd = QtqIconvOpen(&asciiCode, &ebcdicCode);

But when the actual iconv call was executed, with a 
verifiable ASCII string in buffy, muffy came out with 
garbage, and it was different garbage depending on whether 
I set asciiCode.CCSID to 850, 437, or 819.
        out_size = 255;
        inptr = buffy;
        outptr = muffy;
        memset(muffy, 0, 256);
        iconv(cd, &inptr, &in_size, &outptr, &out_size);
