+\subsection{SICS Generic Data}
+This is an attempt to create a generic interface between SICS data and 
+clients. At the bottom of it is a auto resizing array of data. Data
+can be entered into this array either manually or copied from data
+sources such as histogram memories or scans. Data assembled in this
+way, for instance through scripts, can then be forwarded to clients
+either in UUencoded form or as a zipped array. 
+
+In a later stage this may be extended to support selected mathematical
+operations as well. In another stage this may supersede the uuget and
+zipget methods in the scan, histogram memory and specialized status
+objects. 
+
+This needs a data structure:
+@d sidastruc @{
+	typedef struct { 
+			pObjectDescriptor pDes;
+			int *data;
+			char *dataType;
+			int dataUsed;
+			int currentDataSize;
+	}SICSData, *pSICSData;
+			
+@} 
+The fields:
+\begin{description}
+\item[pDes] The standard object descriptor.
+\item[data] The actual data array. This code assumes that sizeof(int)
+== sizeof(float).
+\item[dataType] An array defining the data type for each element of
+data. Supported are: 4 byte int and 4 byte float.
+\item[dataUsed] is the highest data element adressed so far.
+\item[currentDataSize] is the size of data.
+\end{description} 
+
+This object exports the following functions:
+@d sidafunc @{
+ int *getSICSDataPointer(pSICSData self, int start, int end);
+ 
+ pSICSData createSICSData(void);
+
+ int SICSDataFactory(SConnection *pCon, SicsInterp *pSics, 
+	void	*pData,
+	int argc, char *argv[]);
+
+ int SICSDataAction(SConnection *pCon, SicsInterp *pSics, 
+	void	*pData,
+	int argc, char *argv[]);
+@}
+\begin{description}
+\item[getSICSDataPointer] returns a pointer to the first element of
+start in the data array. It is also ensured that enough space is
+available till end.
+\item[createSICSData] creates a new SICSData structure.
+\item[SICSDataFactory] is an interpreter function for creating and
+deleting SICSData things.
+\item[SICSDataAction] is the interpreter wrapper function through
+which users may interact with the SICSData element.
