SC15: Test that certain attributes are saved across inclusions. 1. Maximum input line length. 2. Special character. 3. Local line number. To test this, we first set the first two attributes away from the default. This will enable us to be sure that when they are restored that they are being restored to their former values and not just set to the default. @=* *! Change the special character. *p maximum_input_line_length = 75 Before include. *i sc15a After include. If the maximum input line length has been correctly restored then the second of the following two lines should give an error, but not the first. 123456789012345678901234567890123456789012345678901234567890123456789012345 1234567890123456789012345678901234567890123456789012345678901234567890123456 If the special character has been preserved, then the following should generate an error. * - This should generate an error if all is well. Preservation of the local line number can be checked by looking at the listing file.
