Using these variables in the code is optional nishan. For Concurrent program these are the two mandatory parameters but in the program there is no need to use. If you want to use also you can use these variables. These are used mainly for handling exceptions.

if any error is comming in ur programming through ur procedure then
these two parameter errbuff and retcode will do following functions.
errbuff: it will provide the buffer memory to error message and write into log and out files
retcode: return the code into buffer memory and write into log and outfiles
