[RBASE-L] - Question on "IF variable NOT IN (list) then"

[Paul Buckley]

I'm having trouble getting this to work and I could use someone else to
point me in the right direction.  I've got the code below:

 

SET VAR vdescription =
'This^is^a^test^string^with^some^words^this^test^string^has^some^words^that^
occur^twice'

SET VAR vslocp1 = (slocp(.vdescription2,'^',(.vcounter1-1)))

SET VAR vslocp2 = (slocp(.vdescription2,'^',(.vcounter1)))

    IF vslocp2 = 0 THEN

      SET VAR vslocp2 = =.vslen

    ENDIF

SET VAR vsget = (SGET(vdescription2,(.vslocp2-.vslocp1-1),(.vslocp1+1)))

 

IF vsget NOT IN (.vwordsfound) THEN

   SET VAR vwordsfound = (.vwordsfound + ',' + .vsget)

ENDIF

 

In the last 'IF' statement (IF vsget NOT IN (.vwordsfound) THEN) it is
adding words that are already in the list, i.e. this, some, words.  If I
replace the statement with, IF vsget NOT IN (this,is,a) THEN, it works fine.
What am I missing?

 

Thanks in advance,
