The first extent of some files (they seemed to be big ones) was sometimes numbered one, instead of zero (the number of the extent is in the field named "ex", at offset 12). Why? Is this legal? The record count field was not an exact record count for the extent (nor could it be). The record count is constrained to be in the range 0 through 128, but an extent can hold up to 256 records. What are the rules for resolving this? The CP/M manual does not seem to discuss this. Hugh Redelmeier (416) 922-1937 {utzoo, ihnp4, decvax}!hcr!hugh
