You may think I should use the last computer because it has DOS already, but the size of my database and because it's on an old Bernoulli 90 MB disk makes it impossible at this moment. I do have 46 3.5-inch diskettes with another version of it, but they would also pose challenges using this older …

Sometimes those newer compilers have bugs with targeting older CPUs like 8086 because that support is tested by very few of the users, whereas older compilers that were mostly used on older CPUs are more likely to work, so newer isn't necessarily always 100% better. That might be the case and a …

X-Wing required a 386. False - X-Wing will run on a V20 with an EMS board. Well, if you say so. However, this is a very special setup. The package says system requirements: 386. Of course, it could also be because the publisher wanted to put less effort into support, so he wrote that it works with …

... While in principle this does work, I can compile and link an executable file that I can load both as a .SYS and as a .EXE, I'm shocked to find out that this compiler, released 5 years after the processor's introduction, does not support 386 code generation -- so that's out.

Thanks. Did you notice the 'i' at the end of 'ifidni'? This means case- i nsensitive. The case sensitivity does not apply to numbers.

Thanks. This hints that result of expression is always a number. If something is not a number, then it's a symbol, and the value of such expression is the address of the symbol. That's why JWASM could not immediately tell "this is not a number", it hoped to find the address of the symbol, that's why …

One more question Can you tell me, which if##### key word corresponds to which if operator of the following list? EQ = equal NE = not equal LT = less than LE = less or equal GT = greater GE = greather or equal Now i know, that ifidni , can be used instead of IF ( parm1 EQ parm2..). But the others?
