Routines (alphabetical) > Dot Commands > .RNEW

# .RNEW

The .RNEW command compiles and saves procedures and functions in the same manner as .RUN. In addition, all variables in the main program unit, except those in common blocks, are erased. The -T and -L filename switches have the same effect as with .RUN.

Note: .RNEW is an executive command. Executive commands can only be used at the IDL command prompt, not in programs.

## Example

Some statements using the .RUN and .RNEW commands are shown below.

Statement | Description
`.RUN` | Accept a program from the keyboard. Retain the present variables.
`.RUN myfile` | Compile the file `myfile.pro`. If it is not found in the current directory, try to find it in the directory search path.
`.RUN -T A, B, C` | Compile the files `a.pro`, `b.pro` and `c.pro`. List the files on the terminal.
`.RNEW -L myfile.lis myfile, yourfile` | Erase all variables and compile the files `myfile.pro` and `yourfile.pro`. Produce a listing on `myfile.lis`.

## Syntax

.RNEW [File1, ..., Filen]

To save listing in a file:

.RNEW -L ListFile.lis File1 [, File2, ..., Filen]

To display listing on screen:

.RNEW -T File1 [, File2, ..., Filen]
