This sounds like too simple to ask, but how do I do this?

if I do in instr 0:

gSfilepath    = "../samples/4notesMono.wav"  ; is this the correct way 
to initialize a string variable?

and then try to print it like:

  prints "%s", gSfilepath

I get the following error:

error:  Unable to find opcode entry for 'prints' with matching argument 
types:
Found: (null) prints SS

prints gSfilepath  

or

printf_i “%s”, 1, gSfilepath

hmm, I still have a problem. gSfilepath is a global variable, as the 
name implies, so I initialize it in instr 0 as

gSfilepath init ""

Then later in some instrument, I assign the real string:

gSfilepath = "xxxxx"

but then the prints after that prints nothing...

The printf_i also complains:

  printf_i “filepath: %s”, 1, gSfilepath

gives:

Error: character ?(e2)

error: syntax error, unexpected ERROR_TOKEN, expecting NEWLINE or ','  
(token "?") from file reversalCab2.csd (1)
  line 158:
 >>> printf_i ? <<<
Parsing failed due to invalid input!

Works here:

 gSfilepath  init "" 

instr 1
gSfilepath = "hello/hi/how/are/you"
prints gSfilepath 
printf_i "\n%s\n", 1, gSfilepath 
endin

…

new alloc for instr 1:
hello/hi/how/are/you
hello/hi/how/are/you
