HP-71B IMAGE and PRINT USING

[J-F Garnier]

Hi Garth, I entered your statements and they seem to work as expected:

Code:

10 DIM I$[256]
790 'IMG': I$='6D.D,"Hz    V3=",SDD.D,"dB ",S3D,"'&CHR$(248)&'",4X,'
795 I$=I$&'"V6=",SDD.D,"dB ",S3D,"'&CHR$(248)&'",'
800 I$=I$&'4X,"V6-V3=",SDD.D,"dB ",S3D,"'&CHR$(248)&'",'
805 I$=I$&'"   V7=",SDD.D,"dB ",S3D,"'&CHR$(248)&'"'
820 PRINT USING I$;250,2,-13,4,-27,2,-14,-0,-44

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

Note that the result doesn't exactly match your sample printout.

PRINT USING is one of the most complex and confusing feature of the HP BASIC in general (not only the HP-71B).
