:File Comparison Utilities Under ZCPR2

Tw� utilitie� ar� provide� wit� ZCPR� t� compar� files� �
Both utilities are simple in form to use. These utilities are:

COMPARE -- Compares two files by reading one, computing its
CRC value, saving its CRC and size, and then
reading the other and seeing if they match

DIFF -- Prints out a difference listing between two files;
different bytes encountered at the same
relative displacements from the beginning of
th� file� ar� printe� i� hexadecimal�
decimal, and ASCII forms

These commands are invoked by the following forms:

COMPARE or COMPARE // <-- Print Help
COMPARE dir:file1.typ,dir:file2.typ M <-- Compare

DIFF or DIFF // <-- Print Help
DIFF dir:file1.typ,dir:file2.typ M <-- Compare

:CRC Check Utility Under ZCPR2

Th� CRà Chec� Utilit� distribute� wit� ZCPR� compute� CR� �
value� fo� � lis� o� files�� I� use� th� sam� CRà polynomia� �
employe� b� Keit� Peterse� i� hi� CRC� program�� and�� naturally� �
the values come out the same.

Th� CR� Chec� Utilit� compute� th� CR� value� o� � selecte� �
se� o� file� an� print� ou� th� fil� names�� thei� sizes�� an� �
thei� CR� value� i� hexadecimal� � lis� o� ambiguou� file� name� �
ma�� b� provide� t� CRC�� an� i� als� respond� t� � serie� o� �
options.

The general form of the CRC command is:

CRC dir:afn1,dir:afn2,... ooo...

I� al� ambiguou� fil� references�� th� DIR�� prefi�� i� �
optional�� Thi� prefi� ma� b� � name� director� o� � DU�� form� �
The options available under CRC are:

C - Comment Output; the user is given an opportunity
to enter comments for each file

D - Disk Output; send output to the disk file CRC.CRC
as well as to the console

I - Inspect and approve file before CRC is computed

P - Printer Output; send output to the printer as
well as to the console

Thes� option� ma� b� combine� i� an� manne� desired�� CR� �
command of the form "CRC" or "CRC //" prints a help message.
