Hello,
Was already on this list. WriteVal, WriteIf do not really
write anything. They just return the string.
And only string at the global level causes output. If you wrap
it into { } braces it won't generate any output.
So you need to do something along these lines:
N( output = "" );
if( ...)
{
output = output + WriteVal / WriteIf
}
output; // here text is outputted
As I wrote before there will be printf function in one of
the next betas that will allow to print
from inside funciton or nested curly brices
without using string variable as above.
Also WriteVal will be renamed to NumToStr or something like
that. (old will be left untouched
for backward compatibility however)

Subject: [amibroker] Help with WriteIF
function
Hi all,
Can't get the writeif to give commentary when nested in an if
statement. Any help/ideas appreciated.
See below, and thanks in advance.
Regards,
Gary
