hitting major roadblocks

Hi

While I have a gp pari file with two read statements embedded in the top 
of the file, and they work great, everything falls apart, after running 
the "gp2c-run" command and the read statements seem to be causing major 
blowups in the my_gp_pari_program.gp.run file.

Sample script:

read("pf1000");  // HUGE DATA VECTOR

read("ellpool.gp"); // sophisticated elliptic curve program to create a 
rational lattice of points on an given elliptic curve to a set height

do_run() {

for(i=1,pfsz,

   do major work

);

The gp_pari.run file is totally clueless and thinks pfsz (and the huge 
data vector) is totally undefined. And then the program crashes.

How can I fix this?
