Question about "sprintf" "@" "do for"
Hello,
this works:
A1=3D1
A2=3D2
A3=3D3
i=3D1
vari=3Dsprintf("A%.f",i)
print vari,"=3D",@vari
i=3Di+1
vari=3Dsprintf("A%.f",i)
print vari,"=3D",@vari
i=3Di+1
vari=3Dsprintf("A%.f",i)
print vari,"=3D",@vari
do for [i=3D1:3]{
vari=3Dsprintf("A%.f",i)
print vari
}
But I want to have "print vari,"=3D",@vari" in the loop. But it dosen't=20
work. Why can't I use "print vari,"=3D",@vari" in the loop? Is there a=20
solution for?

The @ indicates macro expansion, which only happens once.
And that one time is before the loop is executed.
So whatever value @vari has at the start of loop execution, that
is the value it will have every time through.

You don't need macros for this
do for [i=1:3] {
vari = <whatever>
print vari, ' = ', value(vari)
}

Thanks a lot Ethan, with the keyword "value" I also found the relevant
side in the manuel.

"my" and "our"
Hi, while testing a program, I erroneously declared the same variable twice within a block, the first time with "my", the second time with "our": { my $fz = 'VTX_Link'; .... ( around 200 lines of code, all in the same block) our $fz = 'VTX_Linkset'; ... } So the initial contents of the $fz declared with "my" is lost, because "our" creates a lexical alias for the global $fz, thus overwriting the previous "my" declaration. It was my error, no question. But I wonder why Perl doesn't mention this - even with "use s...
"out" and "in out"
Hi i found the following explaination: In Ada, "in" parameters are similar to C++ const parameters. They are effectively read-only within the scope of the called subprogram. Ada "in out" parameters have a reliable initial value (that passed in from the calling subprogram) and may be modified within the scope of the called procedure. Ada "out" parameters have no reliable initial value, but are expected to be assigned a value within the called procedure. What does "have no reliable initial value" mean when considering the "out" parameter? By c...
