[Coco] File size from Disk Basic

[theother_bob]

Cool... well *IF* I do another update to Color FOG I plan to incorporate it and your name will appear in the "liner notes". I have been gathering little routines like this and the one on OS-9 disk types for potential use in a future release. Anything to add a little functionality and/or ease of use. Any future version will require *major* rework of my code though. I have to break it into smaller modules as I have already exceeded memory limits to allow full functionality... try making a floppy with 60+ files on it and then select 20 of those files to copy to another disk. Just be careful which disks you try that with. ;-) Actually not much danger of a corrupted disk, but still, be careful.

Cheers,
Bob

Hi, Bob.

The programme snippet I typed will use no extra memory at all. It will use 
the existing File Control Block memory which has already been allocated by 
Disk Basic.

The revised programme lines are:

10 OPEN"D",#1,"FILENAME.BIN",1
20 SIZE=LOF(1)
30 PRINT"FILE SIZE=";SIZE
40 CLOSE #1

You can of course modify that to give you the size in HEX if that is more 
useful.

BTW, the utility "Disk Util 2" by Jeff Francis (sp) also gives this 
information as well as a list of the granules used.

Hope it helps.
