2.2.23 Output to a File
The following example illustrates one way of saving CoCoA output to a
file.
example
Use R ::= Q[t,x,y,z];
I := Ideal(t^2-x,t^5-y,t^7-z);
G := GBasis(I);
G;
[t^2 - x, -tx^2 + y, -x^3 + ty, -xy + z, -ty^2 + x^2z, txz - y^2, y^3 - tz^2]
-------------------------------
D := OpenOFile("MyFile"); -- open "MyFile" for output from CoCoA
Print G On D; -- G is appended to the file "MyFile"
Close(D);
Text can be read from files using
OpenIFile
and
Get
, and commands
can be executed from files using
Source
(or
<<
). One may also
keep a log of a CoCoA session (see
OpenLog
)
