How to add a comment in Staad_Pro from Openstaad? is there any way to set the "*" through commands?

At this moment, there is no OpenSTAAD function available to add a comment line in STAAD input editor. Though it is not possible using any OpenSTAAD function, still you can add any comment using Windows function. As .std file is nothing but a text file, you can read and add/remove anything in this file using batch file. There are several functions/codes available which can read and edit text files - use any such code.
