Specifies IBIS interface file. There
is no output file. Results of MF are
written in INP. Graphics-1 files may
also be processed, using the "GR1DIM"
parameter.
FUNCTION
this keyword specifies the function to be applied, and the columns to
which it applies. Functions are delimited by double quotes. "C"
followed by a number indicates the columns used as input or output.
Up to nineteen columns can be used as input. The term INDEX can be
used in the arithmetic expression to introduce row number into the
calculation (see examples). A special notation is used for column
statistics (see examples). By using "," separator, several
functions can be placed in one call (i.e. FUNC=("C1=INDEX","C2=C1*C1").
Maximum number of columns in one execution is 50.
Also, to support GRAPHICS "GF" capabilities, the "POLY" operator may
also be used. This function returns the polygon number of the
current row (which starts at 1), or a zero if end-of-polygon. To
further support MF as a replacement for GF, the columns may be
referenced by "Xnnn" rather than "Cnnn" to indicate coordinate value.
GRAPHICS-1 files do not have any explicit dimensions in the file label. This allows the user to properly dimension a graphics file so that it may be used by this program. IBIS-2 format graphics files do not need or use this.
This keyword indicates whether to SKIP or INCLUDE rows in which all values are zero. This is primarily used for GRAPHICS files, in which an all-zero row signals "pen-up" or next polygon. NOTE: the #MEAN type column operators do not honor this keyword, and will write a value in every row. The POLY function always skips zeroes, while the INDEX function honors this keyword.
