SYMSS is similar to SYMS except that it plots "smoothed" characters using the software linetype generation routine LINSEQ. Smoothing improves the appearance of most of the fonts when the characters are plotted at large scale. See SYMS and LINSEQ for additional details.
rlen = SYMSS (x,y,h,s,a,n,i,al,l1,l2,l3,l4,l5)
x,y (R): string position (x,y returned if i=-2 or i-3)
If x=999 then x continued from from last position in
prior SYMS call. If y=999 then y continued.
h (R): height of the string to be printed
s (C): text to be plotted
a (R): angle at which the string is to be plotted
n (I): number of characters in string s
i (I): centering flag
= -3 : same as -2 but string is not plotted and
last position is not affected
= -2 : same as -1 but returns end point in x,y
= -1 : (x,y) is lower left corner of plotted array
= 0 : (x,y) is center of plotted array
= 1 : (x,y) is lower right corner of plotted array
= 2 : no plotting, plotted length of string returned
al (R): smoothed arc length (typically 0.05 to 0.01)
l1-5 (I): LINSEQ arc type, use l1=0 for a solid line.
rlen (R): (returned) length of plotted text string
