P [#] Position on Record/Data Block

PBnnn For SAM Files: Position to Buffer.

Position the window at the buffer with the specified number. The display will begin with the first record in the specified buffer. The size of the buffer for SAM files is dependent on the blocksize of the file, and is a multiple of 2048 bytes. Instead of PBnnn, the command #Bnnn can also be given.

Notes:

For very large SAM files, the PB command allows the window to be positioned at the end of the file much more quickly than using the normal ++ command, since PB will read the respective block directly.

When positioning to SAM buffers, CFS loses track of the record numbers. NN mode (No Numbers) is then set automatically.

PPnnn Position to Pam Block.

If the file contains a BLKSIZE = (STD,b) attribute, the command PPnnn will result in the screen being positioned at the PAM block INTEGER(nnn/b).
