Hi Guys, I’m working on a Csound code where I’m trying to convert local string variables to global float variables. I’ve been trying to use both strtodk and strtod , but I keep encountering an error where strtodk reads an empty string. Could anyone help me figure out how these opcodes need to be used correctly to avoid this issue? Below is the code snippet I’ve been working on:
<CsoundSynthesizer>
<CsOptions>
-odac
</CsOptions>
<CsInstruments>
sr = 44100
ksmps = 128
nchnls = 2
0dbfs = 1
instr 2
read:
Sline, kLineNum readf "config.txt"
printk 0,kLineNum
printf "Line %d: %s", kLineNum, kLineNum, Sline
if (kLineNum==1) then
printks "Sline(volume) : %s",1,Sline
kVol strtodk Sline
printks " kVol:%s\n", 1, kVol
gkVol = kVol
printks "global value(float): %f\n",8, gkVol
elseif (kLineNum==2) then
printks "Sline(pause) : %s\n",1,Sline
kPause strtodk Sline
printks "kPause : %s\n",1, kPause
gkPause = kPause
printks "global pause(float) :%f\n",8, gkPause
endif
if (kLineNum<2) kgoto read
turnoff
endin
</CsInstruments>
<CsScore>
i2 0 1 ; Read and store values
</CsScore>
</CsoundSynthesizer>
Here is the error message I’m receiving:
