.FIRST, LAST KEY NUMBER: 4,45
[Enter first and last key under which the measurements
are stored in the document file (it is not possible to
leave gaps).]
.COLUMN #S FOR ABSCISSA, ORDINATE (0=KEY): 2,5
[Enter the columns where x and y are stored.]
.SCALEX, SCALEY (DEF=1): 10.5,1
[Enter the size of the x and y units. e.g. if the key
is used for x each increment by 1 in the key could be
an increment of 10.5 in x.]
.ORDER OF POLYNOMIAL (1-5, DEF=1): 3
[Enter the order of the polynomial that will be fitted to
the data. In the example shown the polynomial
a+bx+cx**2+dx**3 will be used. The output are the
coefficients a,b,c,d. They are printed in the output and
also stored in the (optional) register variables e.g.
[a],[b],[c],[d]....]
.CREATE OUTPUT DOCUMENT FILE (Y/N): Y
[If Y is selected the polynomial is calculated over a
specified range and stored as x, y pairs in a document
file.]
.IN INTERVALS OF: 0.4
[Enter interval between the calculated points. Note:
(XMIN-XMAX)/XIN = (TO-FROM)/INTERVAL+1 currently must
not exceed 9999 because only 9999 value pairs can be
stored in a document file.]
.DOCUMENT FILE: DOC002
[Enter name of output document file. The lines in this
Document file will have the format:
KEY 2 x-value y-value. ]
