Compares Absolute and Residual righting arm properties.
    we 250 0 0 10.5
    angles 0 5 ... 80
    limit(1) angle at equ < 10
    limit(2) angle at equ0 < 10
    limit(3) angle at max > 10
    `limit(4) angle at max0 > 10  `limits 3 and 4 may not be used at the same time (program limitation)
    limit(5) angle at ra0 > 40

    limit(8) ABS area from equ to ra0 > 1  `same angle range
    \This print file shows the difference between absolute and residual righting arms.
    \There are three righting arm curves shown.  The first is without a heeling moment
    \and the second two include one.  The only difference between the second and third
    \examples is the change from limit 3 which uses MAX to limit 4 which uses MAX0.
    \In the third example, only the limit summary is printed.
    \Limits are organized in pairs to compare the absolute and residual righting arm
    \properties.  The min/max values are arbitrary and the pass/fail results are not
    ra /lim:att
    \Without a heeling moment, EQU=EQU0, MAX=MAX0, RA0=RA00, and AREA=ABS AREA
    hmmt 250@0, 50@80     `unrealistic heeling moment for demonstration purposes only
    ra /lim:att
    \With the heeling moment, EQU<>=EQU0, MAX<>MAX0, RA0<>RA00, and RES AREA<>ABS AREA
    \Notice that: EQU>EQU0, MAX>MAX0, RA0<RA00, and RES AREA<ABS AREA
    limit(3) off
    limit(4) angle at max0 > 10
    ra /lim:att /notab
    \Same case as before but with MAX0 substituted in for MAX and
    \its value matches the 1st case with out the heeling moment.
