HP-71B IMAGE and PRINT USING

No, 150 char dim works as well and the image fields are correct for real values.
The problem is that a complex image field C(..,..) must be used if complex variables are used.
But I'm sure Garth already figured it out :-)

[Added:]
Here is a compact solution with complex fields and values:

Code:

10 DIM I$[150]
155 I$='6D.D,"Hz ",4(3X,K,C(SDD.D,"dB",S3D,"'&CHR$(248)&'"))'
160 PRINT USING I$;250,"V3=",(2,-13),"V6=",(4,-27),"V6-V3=",(2,-14),"V7=",(-0,-44)

   250.0Hz    V3=( +2.0dB, -13ø)   V6=( +4.0dB, -27ø)   V6-V3=( +2.0dB, -14ø)   V7=( -0.0dB, -44ø)
