Compress Array of strings

1

Hi
I have a 1 dimensional array of strings. The size can be dim(xxx). I would like to create a procedure that takes my array as a parameter to subsequently remove all empty strings and move the strings together, and return it - preferably as a pointer.
Can this be done in Clarion?

:frowning: se a LOOP. I’m on my phone so this may not be perfect

StringArrayCompress PROCEDURE(*STRING[ ]  Str),LONG,PROC
N LONG 
T LONG ! Out index 
  Code
  LOOP N=1 TO MAXIMUM(Str[],1)
!Wrong: IF Str[N] THEN CYCLE. Leaves only blanks :(
    IF Str[N] = '' THEN CYCLE.
    T += 1
    IF T = N THEN CYCLE. 
    Str[T] = Str[N]
    Str[N] = ''
  END
  RETURN T  
  ! Return how many found, PROC makes optional

Example

Addr STRING(50),DIM(5)
...
  Addr[1]=Vendor:Address1
   ... [2]=2 ... 3 ... 4
  Addr[5]=Clip(City) & Clip(' '&State) & Clip(' '&Zip)
  IF StringArrayCompress(Addr[]) >= 5 THEN
     ! Print 5 line address smaller
  ELSE
     ! Print bigger if 4 or less lines

Well, as done on a phone it’s pretty impressive. But at first glance it makes good sense. I try.
THANKS

Agree. Good work Carl.

I am also on my phone waiting in my car but I think the line at the top of the loop with the cycle should have a not on the condition.

IF not Str[N] THEN CYCLE.

Or alternatively

IF Str[N] = '' THEN CYCLE.

Dang, I had it IF ~ then “tried” to change to IF ... =' ' but forgot some
