Update libqb.cpp
2 changes here: line 13062: When opening a file for random access, if the LEN is not supplied, it defaults the length correctly, but does not allocate the buffer correctly. The code should reference the record_length in the file struct. Changes in lines 15798-15853: When printing text to the screen, carriage returns in the text are ignored. In sub_file_print, the code for printing to the screen is modified to honor carriage returns.
