Hello. FYI, I see an instruction 'jeq' in used in src64/io.l, but I don't see it described in doc64/asm.
Hm, for that matter, I don't see 'jne' or 'jgt' either. Maybe I shouldn't expect to find 'jeq'? I encountered 'jeq' in the 12th line of the definition of testEscA_F (which I pasted below my signature). I guess ^@ is never valid inside a Transient Symbol? : "^@" Bad input '@' ? Nope, it's not valid. Looks like we jumped to badInputErrB. So jeq is some kind of "jmp if ...". But it is different from these? jz adr # Jump to 'adr' if Zero [---] js adr # Jump to 'adr' if Sign [---] jc adr # Jump to 'adr' if Carry [---] What does cmp do to the flags? cmp dst src # Compare 'dst' with 'src' [zsc] Within the flag notation [---] in doc64/asm, What is the difference between . and -? I see that _ is clear. Cheers, thanks, --Dave (code 'testEscA_F 0) do null A # EOF? if s # Yes clrc # Return NO ret end cmp B (char "\^") # Caret? if eq # Yes call (Get_A) # Skip '^' cmp B (char "@") # At-mark? jeq badInputErrB # Yes cmp B (char "?") # Question-mark? if eq # Yes ld B 127 # DEL else and B 31 # Control-character end 10 setc # Return YES ret end cmp B (char "\\") # Backslash? jnz 10 # No call (Get_A) # Skip '\' cmp B 10 # Newline? jnz 10 # No do call (Get_A) # Skip white space cmp B 32 continue eq cmp B 9 until ne loop -- UNSUBSCRIBE: mailto:firstname.lastname@example.org?subject=Unsubscribe
