Like many times, the solution could be very simple. But Im trying to use
strings as Boolean/conditional.

Made an example that generates error in my csound:

error:  error: boolean expression '==' with arg types SS not found, line 14 
Parsing failed due to 1 semantic error!
WARNING: Stopping on parser failure






sr = 44100
ksmps = 128
nchnls = 2
0dbfs = 1
giSine       ftgen     0, 0, 2^10, 10, 1

instr 1
asig oscil .5, 440, giSine
Senv = p4
if (Senv == "Expon") then
kenv expon 1, p3, 0.001
asig = asig*kenv
endif
outs asig, asig
endin



i 1 0 1 "Expon"

I don't think we have an opcode for that.  You could maybe use:

if ( strcmpk(Senv, "Expon") == 0 ) then

:) Glad that works for you.  I think because Strings don't really have
a rate, it might be better to use strcmp and strcmpk rather than try
to figure out some kind of magic with implementing a == opcode.  Nice
that there's a solution that works well. :)

More on strings, is there a way to send strings in p-fields in schedkwhen, I
know they only accept i rate values. But maybe there is a way to convert the
string to a number before csound compiles the code.

Im looking to use strings more to make the code more comfortable to watch, I
know macros is a possibility, but Im curious is strings are also possible to
use for same purpose.

example:
schedkwhen ktrigger, 0, 1, "flute", 0, 2.5, "a3", "ppp"

You can use scoreline as well, which takes the whole event as a string. You can construct the string with sprintf/k.

you could probably also use strset?
if you prefer, you can also set strset declarations in the CsOptions via 
--stresetN=value, for instance --strset1=one --strset2=two.
