I tried using assembly code (
https://ls2.cmich.edu/cgi-bin/wa?A2=ind9806&L=C370-L&P=968 ) to call it but
still I get a protection exception.
I tested with:
void main() {
SVC_REGISTER *r15 = NULL, *r00 = NULL, *r01;
char dsname[44] = "IBMUSER.TESTUP";
char volume[6] = "S6SYS1";
r01 = malloc(16);
memset(r01, 0, 16);
memcpy(r01, "\xc1\x00", 2);
r01 += 4;
r01 = (unsigned int*)dsname;
r01 += 4;
r01 = (unsigned int*)volume;
r01 += 4;
r01 = malloc(140);
CCasvc(27, r15, r00, r01);
}
What am I doing wrong?
