Matching CIAO and CALDB VersionsCIAO 4.1 requires CALDB 4.1 to operate properly. CALDB 4.1 should not be used unless you are running CIAO 4.1. Are your versions mismatched? Update CIAO and CALDB! 03 Nov 2009 A new version of the Contributed Scripts and Modules tarfile has been released; download the updated package from the Scripts page. 02 Oct 2009 CIAO 4.1.2 is not officially supported on the Mac OS X 10.6 (Snow Leopard) platform, but there is a workaround for installing the software in the Unsupported Platforms section of the Platforms page 17 Sep 2009 CALDB has been updated to v4.1.4. Information on the release is available from the CALDB 4.1.4 Release Notes and How CALDB 4.1.4 Affects Your Analysis. |
Ahelp for CIAO 4.1To learn how to use the help system for CIAO, type: unix% ahelp The help documents are accessed by subject (a single word, case insensitive). To get help on the tool dmextract: unix% ahelp dmextract To search on a word, use about (it is an alias to ahelp -k) which will bring up a list of all matching documents or - if there is only one match - display that document. Here we look for any document on "stacks":
unix% about stacks
--------------------------------------------------------------------------------
| SUBJECT | CONTEXT | SYNOPSIS |
|--------------|---------|-----------------------------------------------------|
| parameter | concept | Describes the parameter interface used by CIAO. |
|--------------|---------|-----------------------------------------------------|
| stack | concept | How to set a parameter to more than one value |
| | | using a stack. |
|--------------|---------|-----------------------------------------------------|
| stk_build | tools | stk_build is used to build a stack from a |
| | | user-defined string. The output is to stdout, |
| | | stderr, or a file. |
|--------------|---------|-----------------------------------------------------|
| stk_count | tools | stk_count is used to count the number of items in |
| | | a stack. The output is to the stk_count parameter |
| | | file. |
|--------------|---------|-----------------------------------------------------|
| stk_read_num | tools | stk_read_num is used to read one element of a |
| | | user-defined stack. The output is to the |
| | | outelement field of the stk_read_num parameter |
| | | file. |
|--------------|---------|-----------------------------------------------------|
| stk_where | tools | stk_where finds the location of an item in a stack |
--------------------------------------------------------------------------------
Use "ahelp subject" ("ahelp context subject" for non-unique cases) e.g.:
ahelp stk_where
ahelp tools stk_where
In general you will be now be able to say "ahelp <subject>" to read the help for that document. However, if the same subject matches different contexts, you have to say "ahelp <context> <subject>" as described at the end of the list of matches ("ahelp tools stk_where"). Read the ahelp document for more information on the ahelp system, such as reading parts of the document - e.g. only the examples or the parameter list. |
