Control code

Also, if inside variable ' LCNTL' is .TRUE. Control character is assumed to be effective and reach with the top and can paint a grant subscript ( 2.4.4 section Reference). For instance, at the time of the value that the character number of a control character has been done Setting with a 2.4.4 section

$ {\rm (X_{i})^{2} } $

To paint that

' (X_i ")b2 "'

I am not able to omit the control character that reaches with (the most last top where it is sufficient to designate that and show the end of the mode of a grant subscript). Whether or not the designation method of a control character adequate Subordinate position routine SZQTXW that requests the length and the height of a character checks it. Therefore, when a designation method is not adequate an error message It is output from SZQTXW .
