Hi all,
being that I'm used to C-style languages, when I use Csound and I need to make a loop construct, often I begin to write something like:

for (i1 = 0; i1 < ksmps; i1++) ...

but then I remember that Csound doesn't have a 'for' statement (and it doesn't neither have the '++' operator) and have to rewrite it with a while...

The problem I have with the while construct is that sometimes I forget to write the increment statement, so when I run the code, the while goes in an infinite loop... :-D

I love the C-style for construct, because it's compact and because its particular syntax help me to not forget to specify the increment statement. So I thought I could make something similar in Csound with its macro system and I want to share my results with you:

; ADD "FOR/NEXT" STYLE SYNTAX TO CSOUND:
#define FOR(initialization'condition) #
    $initialization
    while ($condition) do
#

#define NEXT(increment) #
        $increment
    od
#

If you place these two define in the global area of your code, then you could write something like:

$FOR(i1 = 1 ' i1 <= 10)
    printf_i "For iteration number: %d\n", i1, i1
$NEXT(i1 += 1)
