% The .err_exp file is for non-debug grades without --intermod-opt.
|
|
% The .err_exp2 file is for all grades with --intermod-opt.
|
|
% The .err_exp3 file is for debug grades without --intermod-opt.
|
|
%
|
|
% The presence of --intermod-opt yields a kind of error message
|
|
% which makes the presence or absence of debugging irrelevant.
|
|
% However, without --intermod-opt, debug grades affect the error message
|
|
% by causing the implicit import of table_builtin.m (for I/O tabling),
|
|
% which causes the implicit import of io.m, which causes the implicit import
|
|
% of string.m.
