Good evening gurus!

Why is the minimal example failing? i.e. executing always the else-branch?

\doifempty(else) doesn't expand the argument and any argument counts as not empty. To satisfy the command you can expand the first argument (\normalexpanded) or you use \doifnothing(else) which expands the argument. \starttext \startbuffer \doifemptyelse{}{YES}{NO} \doifemptyelse{\empty}{YES}{NO} \normalexpanded{\doifemptyelse{}}{YES}{NO} \normalexpanded{\doifemptyelse{\empty}}{YES}{NO} \doifnothingelse{}{YES}{NO} \doifnothingelse{\empty}{YES}{NO} \stopbuffer \typebuffer \getbuffer \stoptext Wolfgang

\setuppapersize[A6][A6]

\setvariables [Test] [Number=]

\starttext Value of variable Number before test: \getvariable{Test}{Number} \crlf

\doifemptyelse{\getvariable{Test}{Number}} {\dorecurse {5} {TEST} } {Nothing defined \par Contents of variable Number: \getvariable{Test}{Number} }

\stoptex
