1.

Function

2.

Call

CALL SWSWDI(IWDIDX)
CALL SWSCLI(ICLIDX)

3.

IWDIDX	(I)	An index for line width. See SGPACK (Section 1.7.1).
ICLIDX	(I)	An index for line color. See SGPACK (Section 1.7.1).

Notes

(a)

These routines must be called before the actual graphics routine.

(b)

When IWDIDX and ICLIDX is 0, it is treated as 1 in the processing.

(c)

The line width in GRPH1 is specified with a number from 0 to 9. In a device for which color cannot be specified, the line color index ICLIDX may be converted into line width index IWDIDX, so in such a system, the IWDIDX takes values up to 99.

(d)

What color or how thick a line actually is is system-dependent.
