The mvBase system provides a number of system commands for managing files and manipulating the items contained in files. These commands are used for creating, editing, copying, deleting, and clearing files.
The file management commands are:
CLEAR-FILE |
Clears the primary file area occupied by the data file or dictionary. (It does not de-allocate the space, however, as does DELETE-FILE.) It also releases linked frames, returning them to the overflow area. |
COPY |
Copies items to other items in the same file or in another file. It can also be used to copy items to a line printer or a terminal. |
COPY-FILE |
Renames and/or moves files to a new dictionary. After executing COPY-FILE, the original file is deleted. |
CREATE-FILE |
Creates new dictionaries and data files in an account by allocating the file’s primary space. |
DELETE |
Deletes specified items from a file. |
DELETE-FILE |
Deletes the file dictionary, the data file, or both, from the account. All frames allocated for the file are released. |
EDIT and DE |
Create, modify or delete individual items in a file. EDIT (or ED) is a line-oriented editor based on the standard MultiValue Editor, and DOC-EDIT (or DE) is a full-screen editor. |
MOVE-FILE |
Moves a file from one account to another. It sets the group update flags so that incremental saves will work properly. |
RENAME |
Changes the name of the dictionary portion of a file, the data portion of a file, or both. It sets the group update flags so that incremental saves will work properly. |
