Hellow, I have a string and I want to make case depending on it's first
character, like :
#switch (substr(myString,1,1)) str
#case ("s","S") #local ret=vStart; #break
#case ("e","E") #local ret=vEnd; #break
#case ("c","C") #local ret=vEnd; #break
#else #error "[!] Unknown logo fade type\n\n"
#end
how can I do this ?
--
#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M

You'll have to do it this way:
#switch (asc(myString))
#case (asc("s"))
#case (asc("S")) #local ret=vStart; #break
#case (asc("e"))
#case (asc("E")) #local ret=vEnd; #break
#case (asc("c"))
#case (asc("C")) #local ret=vEnd; #break
#else #error "[!] Unknown logo fade type\n\n"
#end

or
#switch (asc(strupr(myString)))
#case (asc("S")) #local ret=vStart; #break
#case (asc("E")) #local ret=vEnd; #break
#case (asc("C")) #local ret=vEnd; #break
#else #error "[!] Unknown logo fade type\n\n"
#end

Of course... How I didn't think of that?
On the other hand, it might have been good to show how multiple cases
executing the same code are used in a #switch structure, as it may not be
very well known.
