Seeking to the start of the coordsys line in a MIF file and overwriting may
not be safe as the clause has variable length and there may not be enough
space for your new text. Although it sounds a waste of processing, the only
safe way of doing this is re-exporting the MIF file from MapInfo or
line-by-line file copying with replacement.
There is indeed no seek() function native to MapBasic. It's pretty straight
forward in a DLL, especially in C where this function has been a long
standing part of the standard run-time library,
