Retrieve(filename, label)

Parameters

filename

-

string ; filename for document to open

label

-

string ; label of expression to retrieve from document

Description

• 

The Retrieve command scans a document file for the given label and returns the corresponding expression.

• 

If filename is not an absolute filename, the setting of currentdir determines what directory to search.

• 

label is an internal label for the expression in the document and does not correspond to equation numbers.

• 

In order to create a such a reference, use Insert>Reference in the Standard Worksheet Interface. This will allow you to look up an expression based on its equation number and automatically generate the internal label.
