5.1.27 dump
Syntax:
dump ( link_expression )
Type:
- none
Purpose:
- dumps (i.e., writes in a "message" or "block") the state of the SINGULAR
session (i.e., all defined variables and their values) to the specified
link (which must be either an ASCII or ssi link) such that a
getdump can retrieve it later on.
Example:
| ring r;
// write the whole session to the file dump.ascii
// in ASCII format
dump(":w dump.ascii");
kill r; // kill the basering
// reread the session from the file
// redefining everything which was not explicitly killed before
getdump("dump.ascii");
r;
==> // coefficients: ZZ/32003
==> // number of vars : 3
==> // block 1 : ordering dp
==> // : names x y z
==> // block 2 : ordering C
|
Restrictions:
- For ASCII links, integer matrices contained in lists are dumped as
integer list elements (and not as integer matrices), and lists of lists
are dumped as one flatted list. Furthermore, links
themselves are not dumped.
