file text open
Allows you to open a text file for writing.
Format:
file text open |
|---|
file_name = | string |
open_mode = | open_mode |
Example:
file text open & |
|---|
file_name = | "c:\data.txt" & |
open_mode = | append |
Description:
Parameter | Value Type | Description |
|---|
file_name | String | Specifies the name of the input or output text file. |
open_mode | Open_mode | Specifies the mode in which the file is to be opened, thereby determining which operations are valid for this file. Available values are: APPEND and OVERWRITE. |
Extended Definition:
1. Depending upon the open_mode the file can either be overwritten completely or appended.
2. You may use the file_name later in file text write or file text close commands to indicate which file you wish to operate upon.
The proper extension for file_name parameter is the default (.txt) but can be overridden simply by supplying a different extension.
You do not need to enclose the file name in quotes if it only contains alpha-numeric characters and starts with a letter. If you want to include other characters, such as a '.' for an extension or '/' or '[]' for directory paths, you must enclose the name in quotes.
3. If the file is opened with open_mode=OVERWRITE, any existing file with the name given in the file_name parameter is deleted at the time of the OPEN. If the file is opened with open_mode=APPEND, then any existing file is appended by subsequent WRITEs (the file need not exist for the APPEND mode to work).
