DCL:GRPH1:SGPACK: User Interface:Explanation of Subroutines: Polyline Primitives
Specifies the settings for the polyline drawn by sgplu, sgplv, sgplr.
itype (I) The line type of a polyline (Initial value: 1). itype 1: solid line; 2: dashed line; 3 dotted line; 4: alternate long and short dashed line. For all other integers besides 0, the last N bits are used to specify the line type by bit pattern. (N is a value set by the internal variable 'NBITS'. The initial value is 16; See Section 2.4.4.) For example, when N=16 and itype = Z'0000F0F0' (hexadecimal constant), the type of the dashed line is '4bits ON 4bits OFF 4bits ON 4bits OFF'. The length of 1 bit is set by the internal variable 'BITLEN'. For examples of line types, see Section 8.1.1.
