Hi,
I have a file that has "cr" (0x0D) terminators on each line.
If I have the line in "myLine" and do this:
repeat with myIndex = 1 to the length of myLine
if char myIndex of myLine = cr then
--do something at end of line
end if
end repeat
It never finds the cr. I looked in the file and conformed that the
lines end in a single cr character.
When I did a charToNum() on cr is returns 0x0A which is a lf!!!!!
Internally in Rev, all line delimiters are LF, showing Rev's unix
heritage. When Rev writes a text file to disk, it converts the line
delimiter to whatever is the convention for the host OS--ASCII 13
for Mac, ASCII 13 + 10 for Win, and ASCII 10 for *nix. Conversely,
when it reads text files, it converts line delimiters to ASCII 10.
What gives? How can I find the real cr is a variable?
It's because I'm not reading the file with RunRev, it's coming in via
an external I've written to get around the >2GB File Limit problem in
RunRev.
So, how can I get the *Real* Value of cr??
In the real code, I have a ReadUntil() function, this takes a
character parameter for the "until" character. The function is
defined like so:
function ReadUntil theFileForkRef,theUntilChar,@theDataBuffer
and I call it like so:
put ReadUntil(myFileForkRef,cr,myDataBuffer) into myOSStatus
Thanks a lot
All the Best
Dave
