Volume 2 Chapter 11 Text Menu *PAGE
*PREFCODE is used to test for entries having a specified previous reference code.
CSD Contents
In certain rare cases it is necessary for CCDC staff to change a reference code.
For example, suppose the CSD contains :
ABCDEF entry corresponding to compound X
PQRSTU entry corresponding to compound Y
Suppose it is discovered that X=Y then the reference code PQRSTU will be changed to, for example, ABCDEF01.
The old reference code is retained in the CSD as the previous reference code and this field is searchable.
Graphics QUEST3D Procedure
Select *PREFCODE from the TEXT sub-menu and respond to the standard text prompts.
Basic QUEST Procedure
Ex.
T1 *PREF 'PQRSTU^' where ^ is blank
This will register a hit for the entry with previous refcode PQRSTU
By enclosing the previous refcode within ' marks and leaving a blank space after U we ensure that a hit is registered only for PQRSTU and not PQRSTU10, etc.
