Uups!
It seem that I advised to do something according to my wishfull
thinking :))

Set path to XXX additive will create non existing path !
Will not report error just set path including word 'additive'
messing up your original path setting
So in case you wish to add additional paths to your path setting
you have to use something like ;

sv_path=set('path')
new_path=sv_path + ';' + 'C:\OtherPicsPath'
set path to (new_path)

Sorry for messleading you in previous message
