3.10.3 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 --
