[SOLVED] DECODE statement with a LOOP statement

I am trying to build a DECODE statement from a string to sort my data. I need to loop through the string and for each data in quotes give it an counter number that start with 1. Can someone please point me in the right direction on how to figure this out.

string: &TC_V1 = 'CA' 'ALC' 'BAL'

Below is what I would like the DECODE statement to look like:

  
SORT/I2 = DECODE DACODE('CA' 1 'ALC' 2 'BAL' 3)

You could try something like:
-* How many items are there?
-* Remove quotes to get a shorter string, which can then be used to calculate the number of items in the string
-SET &SHORT_STRING = STRREP (&TC_V1.LENGTH, &TC_V1, 1, '''', 0, 'X', &TC_V1.LENGTH,'A&TC_V1.LENGTH');
-SET &SHORT_STRING = TRUNCATE(&SHORT_STRING);

-SET &NUM_ITEMS = (&TC_V1.LENGTH-&SHORT_STRING.LENGTH)/2;

-SET &DECODE_ITEMS = ' ';
-SET &CNTR=1;
-REPEAT :LOOP &NUM_ITEMS TIMES
-SET &ITEM = GETTOK(&TC_V1,&TC_V1.LENGTH,&CNTR, ' ',&TC_V1.LENGTH, 'A&TC_V1.LENGTH');
-SET &DECODE_ITEMS = &DECODE_ITEMS | TRUNCATE(&ITEM) | ' ' | &CNTR | ' ';
-SET &CNTR=&CNTR+1;
-:LOOP
-SET &DECODE_ITEMS = TRUNCATE(&DECODE_ITEMS);
-TYPE &DECODE_ITEMS
.
.
.
SORT/I2 = DECODE DACODE(&DECODE_ITEMS);
