	I have this piece of code: if (kgm==1) then ;printks "in if...%s",1, Spath Sbank strsubk Spath, 7, 9 Spres strsubk Spath, 18, 23 printks "bank:%s, preset:%s",1, Sbank, Spres klen strlenk Sbank printk2 klen if (klen>0) then kbank strtodk Sbank ;<= here the output says: empty string kpres strtodk Spres printks "bank:%f, preset:%f",1, kbank, kpres endif endif See the commented line, csound output gives an error about Sbank being an empty string But this is what I try to avoid by the if (klen>0) construction! It looks like the code is already executed??

	Try skipping over it at i-time or initializing it to a non-empty string at i-time.

	I would not know how to skip at i-time, but initializing the string does not work: I get the same error message. Here's the code: instr 11 Spath chnget "GM" printks "now.....%s",1,Spath ;when this line is commented out, the change shows the previous value! kgm changed Spath printk2 kgm if (kgm==1) then Sbank = "0" ;<= initialized here ;printks "in if...%s",1, Spath Sbank strsubk Spath, 7, 9 Spres strsubk Spath, 18, 23 printks "bank:%s, preset:%s",1, Sbank, Spres klen strlenk Sbank printk2 klen ;<= nothing is printed here if (klen>0) then kbank strtodk Sbank ;<= error about empty string here kpres strtodk Spres printks "bank:%f, preset:%f",1, kbank, kpres endif endif endin On 23/11/2020 14:51, andy fillebrown wrote: Try skipping over it at i-time or initializing it to a non-empty string at i-time.

	= is not i-time initialisatio; init is for that. Not sure if that is yur problem though. A complete csd would e so much easier to see what if happening by reading the actual compiled code.

	I fiddled with your program a bit as I do not have cabbage or the sf file you use but the problem is in instr 11 were you use strtodk which runs at both i-time and k-rate. But Sbank is not given a value at init time only on each k-cycle. Thisis because strsubk is also run at i- and k-time so as the range given is ourside the blank string of Spath, Sbank is set to an empty string. Many string operations run at both times which often causes problems ==John ff Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here
