DISCFREE

DISCFREE is a utilit y that reduces the amoun t of fragmen tation on a disc. Fragmentation is a term used to describe the exten t to which ￿les are physically divided up on a disc. As disc space becomes fragmen ted, smaller and smaller amoun ts of contiguous space are a vailable, and ￿les must be broken into smaller and smaller pieces to ￿t. F ragmentation has a negative e￿ect on system performance and is highly undesirable.

You can use DISCFREE to:

Determine free space on the disc.

Perform a START NORECOVERY to correct fragmen tation.

Obtain a detailed format of free space (HISTOGRAM) or free space allocation (ALLOCATION) on discs.

FCOPY/XL

FCOPY/XL is a utilit y program on MPE/iX that allo ws you to copy data from one ￿le to another. You can copy the content of an entire ￿le or a selected portion of a ￿le from an y supported input device to an y supported output device. Supported input devices are disc, magnetic tape, terminal, and tape cartridge. Supported output devices are disc, magnetic tape, terminal, tape cartridge, and line prin ter.

FCOPY/XL's basic functions include: Making multiple copies of ￿les

Making account-independent magnetic tape copies of disc ￿les

Transferring programs or data from one medium to another (for example, from magnetic tape to disc)

FCOPY/XL has many features that expedite ￿le manipulation. These include:

FCOPY/XL code translating function, whic h converts data from one computer code system to another as part of a cop ying operation. F COPY/XL can translate ￿les bet ween ASCII and EBCDIC or BCDIC formats. Y ou can use this feature to prepare magnetic tapes to be used at di￿erent computer installations or to incorporate magnetic tapes from other installations in to your 900 Series HP 3000 system. F COPY/XL can translate bet ween uppercase and lowercase alphabetic characters. This is useful for a peripheral that has only an uppercase character set.

FCOPY/XL subset function, whic h allows you to perform operations using a speci￿ed portion of a ￿le. You can designate the ￿le subset as a range of con tiguous records or as all records containing a speci￿ed data item in speci￿ed columns. This is useful for separating a ￿le into several separate ￿les or cop ying or displa ying only speci￿c records of a ￿le.

FCOPY/XL skip end-of-￿le function, whic h allows you to position magnetic tape to the exact ￿le where you want to read or write.
