fileExists

Purpose
Checks to see if a file exists.

Syntax
fileExists var {filename}

var: The variable to hold the result of the file check. This variable will be set to TRUE (1) if the file exists, or FALSE (0) if it does not.

{filename}: The name of the file to check.



Notes
This command is useful for finding out if a file exists before attempting to read from it.

Example
# load bust list
if ($BustFile <> "")
  fileExists $exists $BustFile
  
  if ($exists)
    setArray $BustList SECTORS
    setVar $i 1
    read $BustFile $bust $i
    while ($bust <> EOF)
      setVar $BustList[$bust] 1
      add $i 1
      read $BustFile $bust $i
    end
  end
end
