Prompt for library ([Do not close others][,Enable conversion by runtime][,Do not open startup task][,Convert without user prompts]) {internal-name (startup-parameters)}
| Do not close others | If specified, the command does not close all open libraries before opening the specified library |
| Enable conversion by runtime | The development version of Omnis offers to convert libraries created by an earlier version of Omnis. If this option is specified, the runtime version of Omnis will also offer to convert such libraries |
| Do not open startup task | If specified, the command does not construct an instance of the startup task when it opens the library |
| Convert without user prompts | If specified, and conversion is allowed, Omnis will immediately perform the conversion without giving the user any prompts that require a response; also, the user cannot cancel the conversion |
This command prompts the user for a library file. You can specify the internal name and startup task construct parameters of the library to be opened, together with the Do not close others, Do not open startup task, and Enable conversion by runtime options.
If the internal name of an opened library is specified, a check is made to ensure the internal name is unique among the open libraries; a runtime error occurs if this is not the case. If no internal name is specified, the default internal name is the disk name of the file with the path name and suffix removed. For example, the internal name for 'hd:myfiles:testlib.lbs' is 'testlib'.
If an attempt is made to open a library which is already open, that library is closed and reopened. Refer to Close Library for the consequences of closing a library. If the user cancels the Select Library dialog, the flag is cleared and no libraries are closed.
Do not close others
The Do not close others option lets you keep open all other libraries. If the Do not close others option is not selected, then all other open libraries are closed when the user opens a new library, including the one containing the currently executing method.
Passwords
If the library does not need a master password, it is opened at the master level, otherwise the usual prompt for password dialog is opened. The library is closed and a flag false returned if this dialog is closed without a password being entered.
Startup task
If the Do not open startup task option is specified, the startup task construct for the opened library is not called and there is no startup task instance. Otherwise, the startup task $construct() method is called and the parameters for it are passed.
Enable conversion by runtime
If you select the Enable conversion by runtime option, and the library was created with a previous version of Omnis, then the runtime version of Omnis can convert the library if the user allows. The default is that an Omnis runtime will not ask the user if they want to convert the library.
