3.9.4 Break points
A break point can be put into a proc by inserting the command~.
If Singular reaches a break point it asks for lines of commands
(line-length must be less than 80 characters)
from the user. It returns to normal execution if given an empty line.
See ~.
Example:
proc t
{
int i=2;
~;
return(i+1);
}
t();
==> -- break point in t --
==> -- 0: called from STDIN --
i; // here local variables of the procedure can be accessed
==> 2
==> -- break point in t --
==> 3
