Eval Qcamk = \BLANKS Qcaerved = \LOVAL | IBM Version 4 instruction

C\ Beginning of mainline C\

C\ Initialize the error code parameter. To signal exceptions to C\ this program by the API, you need to set the bytes provided C\ field of the error code to zero. Because this program has

C\ exceptions sent back through the error code parameter, it sets C\ the bytes provided field to the number of bytes it gives the C\ API for the parameter.
