Re: hitting major roadblocks

[American Citizen <website.reader3@gmail.com>]

To all:

Here's what I had before in my gp pari script at the very top of my 
file. This worked okay normally in interactive gp.

read("pf1000");

read("ellpool.gp");

And I hit errors when compiling with the gp2c-run command.

Here's what fixed the problem.

#1. I explicitly took all pertinent code related to the 
"ellcntpool(e,p,cnt)" function and put that code into the pari script.

It took 3 runs since there were dependencies of that command upon other 
gp pari commands, but I was able to finally put all the gp pari code 
into the script as a complete set, with no outside dependencies.

#2. I was able to read the huge pf1000 file into one of the pari script 
functions as follows

> do_run(pfname) = {
> my(v,e,E,p,k,pf,pfsz);
> if(pfname==0,print("Need pf file name.");return(););
> [pf,pfsz]=readvec(pfname);
This enable me to select any pf file ( I have several such as pf100, 
pf500, pf2000, etc) where pf is primitive fraction list and execute the 
do_run() command.

This successfully passed the "gp2c-run" command and come up with 
functional pari script run code.

This is to let you know what works.

And thank you Bill for responding to my post, it is appreciated.
