Purpose
To input data to and output data from a Curves Data Store.
Syntax
|
CDS ( APPEND $W ) < $F > |
Description
The Curves Data Store (CDS) is primarily used to transfer curve data to other Initial Design systems.
Command Qualifiers
|
APPEND |
Store the data for the current curve in the CDS with the given name. If the curve already exists then it will be overwritten. |
|
CLOSE |
Close the CDS. |
|
DELETE |
Delete the named curve from the CDS. |
|
DIRECTORY |
Output a directory list of the curves in the CDS. This can optionally be sent to a file by using the /FILE qualifier. |
|
EXTRACT |
Extract the data for the named curve from the CDS and make it current. The curve is made current and assigned the user selected curve type. If the curve is extracted as an orthogonal curve then it must be truly orthogonal, its position will be determined from the constant element of coordinates. |
|
OPEN |
Open a CDS with the given name. When a CDS is opened the contents are copied to a workfile. Only when a SAVE is performed is the original data store updated. |
|
SAVE |
Updates the CDS with the current contents of the workfile. |
|
/NEW |
Create a new PDS with the given name. If the option is not used then the PDS must already exit. |
|
/NOSAVE |
Modifications made to the CDS since it was opened will be discarded. |
|
/READ_ONLY |
Open the PDS for read only. |
|
/SAVE |
