end -- stop loading a file

Synopsis

• Usage:

  end

• Consequences:

  • This symbol, encountered at top level, causes loading of the current input file to be stopped.
  • Alternatively, in the debugger it causes the current code to be abandoned, and the debugger to be re-entered one level further up. If there are no more suspended levels of execution, then control is returned to the top level.

Description

i1 : load "Macaulay2Doc/demo3.m2"
hi

i2 : get loadedFiles#(#loadedFiles-1)

o2 = print hi
     end
     print ho

Here is an example of its use in the debugger.

i3 : load "Macaulay2Doc/demo1.m2"

i4 : g 2
/usr/local/share/Macaulay2/Macaulay2Doc/demo1.m2:8:12:(3):[2]: error: division by zero
/usr/local/share/Macaulay2/Macaulay2Doc/demo1.m2:8:12:(3):[2]: --entering debugger (type help to see debugger commands)
/usr/local/share/Macaulay2/Macaulay2Doc/demo1.m2:
8:10-8:12: --source code:
     b := 1/x;

ii5 : end
/usr/local/share/Macaulay2/Macaulay2Doc/demo1.m2:13:11:(3):[1]: --entering debugger (type help to see debugger commands)
/usr/local/share/Macaulay2/Macaulay2Doc/demo1.m2:
13:10-13:14: --source code:
     d := f(y-2);

ii6 : end

i7 : g 3
