iffalse /iftrue problem in fms logo

[veter...@hotmail.co.uk]

hi i seem to be having a problem with the command iftrue and iffalse
using the example from the help file i write my code in the form

test pixel = [255 255 255]
iftrue [print [white] ]

but logo returns an error message saying
iftrue without test it does the same for the iffalse as well

This has to be done in a procedure. The following works for me, e.g.

to tst

test pixel = [255 255 255]

iftrue [pr [ok]]
iffalse [pr [no]]
end
