Also, a .LIB libraryfile line must be included in the netlist file.
For example,

.LIB JFETOA.LIB      ;Allows use of all JFET input OP-AMP models.


The models were designed to provide a valuable tool for designers 
which closely mimic the response of the real device while providing
a significant increase in simulation speed over a discrete model.
Here is a list of the parameters modeled and not modeled.

                 Modeled                       
-----------------------------------------
Non-linear input transfer characteristics
Input resistance

Input offset current
Input bias current
Open loop gain
Gain-Bandwidth product
Poles and zeros in the frequency response

Output short circuit current
Output impedance
Quiescent and dynamic supply current

   Not modeled as part of this release
