I am using PCML to call C/400 Program from my Java program. The C

get the returned value. I set the usage in the PCML file to be
inputoutput. Is there a way to get the value that set back in argv[1]
Although I'm not an expert in C, shouldn't each element of argv be specified as a separate parameter in the PCML?

So it would be something like ...

<pcml version="1.0">
<program name="myCProg" path="/QSYS.LIB/MyLib.LIB/MyC_Porg.PGM">
<data name="argv1" type="char" length="100" usage="inputoutput"/>
<data name="argv2" type="char" length="100" usage="inputoutput"/>
<data name="argv3" type="char" length="100" usage="inputoutput"/>

That way, if you set the value of argv[1], you could retrieve the value from the PCML using 'myCProg.argv1'.

Even more problematic is that AFAIK C parameters are not bidirectional. Back in the day at SSA we had to create our own parameter passing technique. It used a stream file to pass parameters between the two programs. Ugh. The flashbacks! THE FLASHBACKS!!!!!
