Well, first of all, jmp simply ‘jumps’ to the label that you give to it (which is a memory address as program instructions are stored in memory) while call stores the location where it will return (below the call instruction) in the stack, jmp to the label, and then at the ret instruction, jmp back … Read more
You would call the sub as EnterCellValueMonthNumber “N23:Q23”, 1 No brackets. Or Call EnterCellValueMonthNumber(“N23:Q23”, 1) Brackets, and Call before it. Also, your Sub is expecting a Range object as the first argument and you’re supplying a string; you should change the signature of the sub to: Sub EnterCellValueMonthNumber(cells As String, number As Integer) Also, I’m … Read more
Do you have a dependency loop? If Perl starts compiling your script and encounters a line like this: use PackageA; Perl pauses the compilation of your script; locates PackageA.pm and starts compiling it. If it encounters a line like this: use PackageB; Perl pauses the compilation of PackageA; locates PackageB.pm and starts compiling it. Normally, … Read more
A Haskell program’s structure is surprisingly simple. You have a main function which does IO, and that’s about it. So the basics: module Main where addition a b = a + b main :: IO () main = do let z = addition 5 3 putStrLn $ “The result is: ” ++ show z Now … Read more
Yes, Fortran has procedure pointers, so you can in effect alias a function name. Here is a code example which assigns to the function pointer “f_ptr” one function or the other. Thereafter the program can use “f_ptr” and the selected function will be invoked. module ExampleFuncs implicit none contains function f1 (x) real :: f1 … Read more
You need to pass it in as a reference: calc(\@array, $scalar) And then access it as: my @array = @{$_[0]};
I’m a frequent abuser of &, but mostly because I’m doing weird interface stuff. If you don’t need one of these situations, don’t use the &. Most of these are just to access a subroutine definition, not call a subroutine. It’s all in perlsub. Taking a reference to a named subroutine. This is probably the … Read more
From the doc: In a Sub or Set procedure, the Return statement is equivalent to an Exit Sub or Exit Property statement, and expression must not be supplied. So they’re the same in this context. (Return (<value>) is used in functions and property.get’s. Obviously slightly different in that context).
