1: Single-precision floating-point data
If 16-bit binary or BCD data is being used, the line-segment data is contained
in words C+1 through C+2m+2. If 32-bit binary or floating point data is being
used, the line-segment data is contained in words C+1 through C+4m+4.
Bits 00 to 07 contain the number (binary) of line coordinates less 1, m–1. Bits
08 to 12 are not used. Bit 13 specifies either f(x)=f(S) or f(x)=f(X
specifies f(x)=f(S) and ON specifies f(x)=f(X
the output is BCD or binary: OFF specifies binary and ON specifies BCD. Bit
15 determines whether the input is BCD or binary: OFF specifies binary and
ON specifies BCD.
