84. *SAVE bug ~~~~~~~~~ It is useful to be able to save very long dummy files when reserving disc space for random access files, (or for other purposes), as recommended in the Acorn DFS User Guide. The syntax is *SAVE 0 N or *SAVE 0+N, where N is the length in Hex. This is very fast, and works fine on the 1.20 Acorn DFS, (DNFS). However, on the 0.90 Acorn DFS, horrible things happen as soon as N exceeds &FF00, (just under 64k), and the disc tends to be corrupted. The alternative is use OPENOUT, and advance PTR# to the required length. In the example below, an 88k file can be reserved, albeit very slowly. The DNFS is much faster than the 0.90 all round, but the difference is particularly noticeable when you are using Random Access Filing, and it's worth upgrading if you can get hold of the EPROM. The Acorn 1770/1772 DFS does not suffer from this problem. Remember that 1k is 1024 bytes, so PRINT &16000/1024 gives the answer 88k. 10 chan=OPENOUT("name"):PTR#chan=&16000:CLOSE#chan
