Re: Segfault using integer index on associative array

Associative arrays need to have a simple character variable for their
subscript - they work completely differently from normal arrays - so you
cant using the old '[' ']' for the subscripts.
I'm not sure what you're after - but you can easily convert an integer to a
character string - so how about something like :

FOR *idx*=1 TO 10  # Incr integer index over array.

LET adx=idx USING "&&&&"
  IF *a_ohvalue**<<adx*>> IS NOT NULL
  THEN
     LET other_var=*a_ohvalue**<<adx*>>
  END IF

END FOR

Although - I dont think thats what you are after!


As far as I know - from 4gl - theres no current way to iterate over an
associative array - so you might be better off to create a temp table or
something similar ?
