- rfile:
-
- Syntax: rfile
- rfile NAME
- rfile NAME1 NAME2 ...
-
- Description:
-
- rfile : Prints a list of all the files with a `.r' suffix. The
- list is compiled by searching the directories
- contained in the environment variable
- `RLAB_SEARCH_PATH'.
-
- rfile NAME : Loads the contents of the file denoted by NAME
- into the workspace. The NAME argument is NOT a string,
- and does not have to include the `.r' suffix.
-
- Allowable names for rfiles are filenames that start
- with:
- A digit, or a letter (a-z or A-Z).
- and contain:
- digits, letters, and/or `-' `_' `.'
-
- You may not be able to use all the possible filenames
- allowed by the host operating system.
-
- If the user's environment does not contain RLAB_SEARCH_PATH,
- then the default search-path is used. The default is set at
- compile time. Normally the default is ".", the current working
- directory.
-
- Rfile is a command, not an expression or statement. Therefore,
- it must be issued on a line by itself, and cannot occur in the
- midst of another statement or expression. See `help COMMAND'.
- The rfile command cannot be continued across lines (no
- continuations).
-
- The command `rfile name' can be used more than once. Each time
- the command is issued the file `name.r' is loaded.
-
- The rfile command tries to be friendly. If you give it a
- string without the `.r' extension, it will automatically add
- one for you. If you give is a string with the `.r' extension,
- it will leave it alone.
-
- The contents of the named file can be any valid RLaB commands
- or functions. There is no limit to the number of functions
- that a file can contain. Additionally, a mixture of commands,
- and function definitions can be included in the same file.
-
- Example:
-
- > rfile roots.r poly bode
