fork/exec/pipe

Hi

I am trying to control to start an octave process where I can write
to it read the output back into perl.

For example I would like to :

1 - Start octave
2 - Write a=1 b=2. Read output into perl
3 - Write a+b. Read output into perl and so on.

Could someone please help me do this.

Thanks

Have a look at the following docs,

perldoc perlipc
perldoc IPC::Open3
perldoc IPC::Open2
perldoc perlopentut

See if they help. In general the above will allow you to avoid messing
with setting up your own pipes, etc. but still allow you to read/write
to a process.  If they don't work you can get lower level but start
there first.
