Can we just please rename all "cx" into something like "len"? Or is
there a real need to have "cx" in there?

if cx is such a nuisance to you, sure, I can rename it to i

better than random characters :)

will be in v3

Also, I still dislike "test_one_sccb". Can't we just just do
something like

expect_pgm_int();
rc = test_one_sccb(...)
report("whatever pgm", rc == WHATEVER);
report("whatever rc", lc->pgm_int_code == WHATEVER);

In the callers to make these tests readable and cleanup
test_one_sccb(). I don't care if that produces more LOC as long as
I can actually read and understand the test cases.

if you think that makes it more readable, ok I guess...

consider that the output will be unreadable, though

I think his will turn out more readable.

two output lines per SCLP call? I  don't think so

To clarify, we don't always need two checks. E.g., I would like to see instead of

+static void test_sccb_too_short(void)
+{
+	int cx;
+
+	for (cx = 0; cx < 8; cx++)
+		if (!test_one_run(valid_code, pagebuf, cx, 8, PGM_BIT_SPEC, 0))
+			break;
+
+	report("SCCB too short", cx == 8);
+}

Something like

static void test_sccb_too_short(void)
{
	int i;

	for (i = 0; i < 8; i++) {
		expect_pgm_int();
		test_one_sccb(...); // or however that will be called
		check_pgm_int_code(PGM_INT_CODE_SPECIFICATION);
	}
}

If possible.
