Editing Applications and Frames
If you are unable to edit an existing application or frame with the Edit operation, read the following sections to try to locate the cause of the problem.
Source Code Directories
Determine the source code directory as follows:
1. In the Applications Catalog window, select MoreInfo from the menu.
The MoreInfo about an Application window displays.
2. Select Defaults from the menu.
The Application Defaults window displays. This window contains the name of the source code directory.
Be sure that:
• This directory exists.
• It contains the source code files for the application.
• You have read and write permissions for the files.
If this directory is incorrect, change it in this window.
3. If you are using Linux and your source directory has disk quota or permission problems, contact the system administrator.
Copying Applications
If you are editing an application that you copied in with the copyapp utility, check the source code directory as described above to make sure that it does not still point to the old location for the source code files. Also, ensure that you have copied the source code files.
System Editor
If you cannot use the system editor to edit source code files or Vision escape code files, take the following steps to make sure that you have defined the symbol ING_EDIT correctly:
Windows:
1. At the operating system prompt, type:
ingprenv ING_EDIT
The default editor command is displayed, if there is one set; otherwise, the default editor is edlin. Be sure the editor is in the PATH, or that the full path to the editor is specified.
2. If this is not the editor you want, change it with the following command:
ingsetenv ING_EDIT editor_name [flags]
In the above command, editor_name is the full pathname of the editor you want to use.
Linux:
3. At the operating system prompt, type:
echo $ING_EDIT
The default editor command is displayed. Be sure the editor is in the PATH, or that the full path to the editor is specified.
4. If this is not the editor you want, change it with the following command:
ING_EDIT = editor_name [flags]
export ING_EDIT
In the above commands, editor_name is the full pathname of the editor you want to use.
