The echo in your code will only run when s2 finishes. To provide $param3 as input, try this instead.

Code:
s2 param1=val param2=val2 <<HERE
val3

HERE

Whether it works or not depends on whether s2 accepts the remaining parameters as standard input; some programs explicitly read from the terminal, or use some sort of interactive front end which doesn't work with standard input.

gsl-randist

GSL-RANDIST(1)						      General Commands Manual						    GSL-RANDIST(1)

NAME

       gsl-randist - generate random samples from various distributions

SYNOPSYS

       gsl-randist seed n DIST param1 param2 [..]

DESCRIPTION

       gsl-randist  is a demonstration program for the GNU Scientific Library.	It generates n random samples from the distribution DIST using the
       distribution parameters param1, param2, ...

EXAMPLE

       Here is an example.  We generate 10000 random samples from a Cauchy distribution with a width of 30 and histogram them over the range  -100
       to 100, using 200 bins.

	    gsl-randist 0 10000 cauchy 30 | gsl-histogram -100 100 200 > histogram.dat

       A  plot	of  the  resulting histogram will show the familiar shape of the Cauchy distribution with fluctuations caused by the finite sample
       size.

	    awk '{print $1, $3 ; print $2, $3}' histogram.dat | graph -T X

SEE ALSO

       gsl(3), gsl-histogram(1).
