Probably I found a solution by myself. For .proc labels, .sizeof() seems 
to return the size of the whole content (until .endproc). So, I can 
define large data on multiple lines enclosing it with .proc and 
.endproc. It is data, not "procedure", but the method seems ok for my 
purpose.

But still there is a strange behavior. I wrote a test code:

   STR:    .byte   "str"
   .proc   myproc
           lda     STR,x
           lda     #.sizeof(STR)
   .endproc

Giving ca65 this code, it causes error: "Size of `STR' is unknown". If 
you comment out the line "lda STR,x", ca65 doesn't cause any error and 
.sizeof() returns 3. And, it seems that there are some ways to suppress 
this error:
   * removing the lines ".proc" and ".endproc"
   * explicitly specify STR as "::STR" (global label)
Is it related to scope?
