1. The string delimiter "\n" is only valid on the Macintosh, e.g if you have got a file with:
1.23 122.33 23.33
12.23 2.93. 9.33
23.33 23.3 243.3
and you read line after line and want stop at: line==999
CountLines:: !File -> !Int
CountLines file = ReadLines 0 file
ReadLines:: !Int !File -> !Int
ReadLines nLines file
#! (line,filerest) = sfreadline file
| line == "999" = nLines
= ReadLines (nLines + 1) filerest
then *this* is only valid on the Sun and on Windows!
2. On the Macintosh the above example would deliver as number of lines a value of 7 BUT on the Sun or on Windows one get 6!
3. A few days ago I posted a file-reading program which reads the above file-scheme. On the Mac everything worked okay but on the Sun it is impossible to get appropiate values and on Windows the programm delivers always the first array value as NaN:
4. It is NOT documented that between: Macintosh, Unix and Windows there is a notable difference between the file handling procedure!
