- # Name : PATCH.TXT
- # Purpose : instructions for using .RTP files to upgrade your version
- # of an IDC product to the current version
- # Created : 02-12-1992
- # Notes :
- #----------------------------------------------------------------------------
-
- The *.RTP file contains only the changes between the version you have
- and the newer version. The patch executable (PATCH.EXE) is needed to
- apply the patch file (whatever.RTP).
-
- The patch executable (PATCH.EXE) is supplied with each IDC product
- distribution disk.
-
- After the product is installed the PATCH.EXE file resides in the
- product directory.
-
- If you do not already have PATCH.EXE, it can be downloaded from
- our bulletin board. There is a copy in each of the conferences for
- your convenience.
-
- Applying the patch:
-
- A. Make sure all files provided with the original product exist
- and are all under a single directory (subdirectories off this
- single directory are ok). If you have used a non-default
- installation then the easiest way to ensure that all files are
- present and accounted for is to INSTALL the product again.
- If you have deleted some files or have moved them to another
- directory, PATCH.EXE will give you an error message: "whatever.ext
- file not found" and drop you back out to the DOS prompt. This is one
- reason we recommend using the default installation
-
- B. The names of the patch files include the version number being
- upgraded from and the version being upgraded to. Patch files
- names for IDL products start with the letter "I", file names for
- Class(y) start with the letter "C".
-
- e.g., I213_214.RTP upgrades IDL v2.13 to v2.14
- e.g., C104_105.RTP upgrades CLASS(Y) v1.04 to v1.05
-
- Make sure you are using the correct patch file for your version.
-
- C. Make sure the patch file (whatever.RTP) is in this single
- product directory (not in one of its subdirectories), or in
- a directory above it, i.e. the root directory.
-
- D. There are 2 ways to run PATCH.EXE from the command line. Both assume
- that PATCH.EXE is either in the current directory or can be found
- somewhere in your PATH= environment variable.
-
- 1. Rename whatever.RTP to "PATCH.RTP" and enter :
-
- PATCH
-
- with no command line parameters. "PATCH.RTP" is the default
- name that the executable expects to find.
-
- 2. Use command line parameters, you must supply 2 of them.
-
- Enter:
- PATCH <path to product directory> <whatever.RTP>"
-
- 1st parameter: <path to product directory>,
- e.g. c:\class(y) or c:\idl(2) or where ever you installed
- it.
-
- 2nd parameter: <whatever.RTP>,
- e.g. C104_105.RTP or 213_214.RTP or whatever patch file
- you are applying.
-
- E. That's all there is to it. As PATCH.EXE runs it will display
- the names of the files being upgraded. When it's done, you will
- have the files that comprise the product version indicated in
- the downloaded patch file name. You can delete the .RTP file, it
- is no longer needed.
