Hi:
Thank you for your help. it worked. Below is an example of a recursive
process:
But i still have a question, how can i do to print inside the procedure
get_factorial without call the subroutine eplprint?. If i try to use
embperl code to define the sub ([$ sub get factorial $]), it does not
work.
[$ sub eplprint $]
[- $c = shift ; -]
[+ $c +]
[$ endsub $]
[*
sub get_factorial
{
local $a;
$a = shift;
if( $a == 1 )
{
&eplprint($a);
return($a);
} else {
&eplprint($a);
return($a*&get_factorial($a-1));
}
}
*]
[- $d= 3; $b=&get_factorial($d);-]
--- "Factorial" of [+ $d +] is [+ $b +]
Thank you
Carlos Kassab
