Creates a block file (used for storing source code and/or data) on the nominated disk, with enough space for size screens/blocks of data and sets the new file as the current blocks file.

80 MKBLK DSK1.BLOCKS

The above creates a file called BLOCKS on DSK1 (of type D/F128) with enough allocated space for 80 screens/blocks.

Note: In version 1.0 and 1.1 the word MKDSK is used, which has a slightly different syntax (though the format of the files created is compatible). Please see MKDSK for V1.0 and V1.1.
