NEC-LIST:Re: PL card

Hello Arie,

I'm a newbie in NEC2 (trying to use it for three weeks now) but I've
found some information about the PL card in a old users's guide for
NEEDS 2.0 (old DOS-program that uses NEC-81 Version 2.2). It looks
like the page about the PL card was added later to the user's guide
(my user's guide is from 1995 - the original from 1989).

> Does anybody have extra information about this "PL" card.

Here is the "hand-typed" information from the NEEDS 2.0 User's
guide (sorry for the long lines):

DATA STORAGE FOR PLOTTING (PL)

Purpose: The PL command sets flags for writing selected output data
into a predesignated file for later plotting.

Parameters:
Integers
        IPLP1 (I1) - data type to be written into auxilliary file.
                     Options are:
                     IPLP1 = 0 No action
                           = 1 Currents
                           = 2 Near fields
                           = 3 Patterns
                           = 4 Impedance, SWR
                           = 5 Admittance, SWR

        Remaining integers depend on data type.
          a. Currents (IPLP = 1)
                IPLP2 (I2) - Wire current component format options are:
                     IPLP2 = 0 No action
                           = 1 Real and imaginary
                           = 2 Magnitude and phase

                IPLP3 (I3) - Surface patch current components options are:
                     IPLP3 = 0 No action
                           = 1 Ix
                           = 2 Iy
                           = 3 Iz
                           = 4 Ix,Iy,Iz
                                   (All measured in magnitude and phase)

          b. Near Fields (IPLP1 = 2)
                IPLP2 (I2) - Near field components format options are:
                     IPLP2 = 0 No action
                           = 1 Real and imaginary
                           = 2 Magnitude and phase

                IPLP3 (I3) - Near field components options are:
                     IPLP3 = 0 No action
                           = 1 X - component
                           = 2 Y - component
                           = 3 Z - component
                           = 4 X,Y,Z component
                           = 5 Total Field (magnitude only)

                IPLP4 (I4) - Coordinate to be stored options are:
                     IPLP4 = 1 X - coordinate
                           = 2 Y - coordinate
                           = 3 Z - coordinate

          c. Far field patterns (IPLP1 = 3)
                IPLP2 (I2) - Angles to be written into auxilliary file options are:
                     IPLP2 = 1 Theta (or Z for RP1)
                           = 2 Phi
                           = 3 Rho (for RP1)

                IPLP3 (I3) - Electric field component options are:
                     IPLP3 = 0 No action
                           = 1 Etheta
                           = 2 Ephi
                                   (Field components in magnitude and phase)
                           = 3 Erho (for RP1)

                IPLP4 (I4) - Power pattern component options are:
                     IPLP4 = 0 No action
                           = 1 Vertical gain (dB)
                           = 2 Horizontal gain (dB)
                           = 3 Total gain (dB)
                           = 4 Vertical, Horizontal & Total Gain (dB)

Notes:
        1. The PL card may be used anywhere between the GE and XQ commands.
        2. A PL card with IPLP = 0 will suspend any previous PL specs.
        3. All the data requested is written out to the a file named F0R008.DAT. Use this file to do plotting.

I hope that is what you are looking for.

Nice "Pfingsten" and Tschoe,
Steff
