bbs.menucmd("GV","ibol;x;y;"+postfile+";END")
Not to worry: I figured it out after reading the "whatsnew.txt" for A47.
For those who find themselves in the same boat, the "GV" menu command has a different format in A47.
The above line should read something along the lines of:
bbs.menucmd("GV","ibol;"+postfile+" /END")
Also note that an updated "ibol.ans" template and a new "ibol.ini" file need to be placed in the mystic "text" directory - these need to be in line with A47's "ansiview.ans" and "ansiview.ini" files, respectively.
There may already be another version of this script out there somewhere, but this should get it working if you're stuck with a pre-A47 version.
