Working with Files and File Systems in Recital

Opening and Creating Text Files in Recital

  • fcreate() - create a new text file, returning a file handle
numeric = fcreate(<filename as character>)
  • fopen() - open an existing text file, returning a file handle
numeric = fopen(<filename as character> [, <mode as numeric>])

Closing Text Files in Recital

logical = fclose(<filehandle as numeric>)

Writing to a Text File using Recital

  • fputs()- write a character string to a text file, returning the number of bytes written
numeric = fputs(<filehandle as numeric>, <string as character> [, <bytes as numeric> [, <terminator as character>]])

Reading From a Text File using Recital

  • fgets() - read and return a line from a text file
character = fgets(<filehandle as numeric> [, <bytes as numeric> [, <terminator as character>]])

===Checking Whether a File Exists in Recital===
* [[FILE()|file()]] - check whether a file exists

<pre>
logical = file(<filename as character>)

Moving, Copying and Deleting Files with Recital

rename <sourcefile as character> [to] <targetfile as character>
copy file <sourcefile as character> [to] <targetfile as character>
  • erase - delete a file or files
erase <filename as character [, filename as character [, ...]]>
delete file <filename as character>

Accessing File Attributes in Recital

  • fileinfo() - return a comma-separated string containing information about a file
character = fileinfo(<filename as character>)
  • fsize() - return the size of a file
numeric = fsize(<filename as character>)
  • fdate() - return the last modification date of a file
date = fdate(<filename as character>)
  • ftime() - return the last modification time of a file
character = ftime(<filename as character>)
character = fullpath(<filename as character>)
character = basename(<filename as character>)

Miscellaneous File and File System Commands and Functions

  • adir() - return number of files matching a pattern and load filenmames and information into arrays
numeric = adir(<skeleton as character> [, <filenames as array> [, <filesizes as array> 
[, <creationdates as array> [, <creationtimes as array> [, <attributes as array>]]]]])
 
  • dir - display a directory of files
dir [<skeleton as character>]
  • filecount()- return number of files matching a pattern
numeric = filecount(<skeleton as character>)
  • curdir() - return name of the current directory
character = curdir()
  • default()- return name of the current directory
character = default()
set default to [<directory as character>]
  • path() - return current Recital path setting
character = path()
set path to [<directories as character>]
  • diskspace() - return the available space on the current disk
numeric = diskspace()
