Hi there,

I'm new to FOCUS and IBI, so please bear with me.

I created a STRREP function to strip out the string ' OR ' and put in commas so that I could pass this parameter to a SQL statement. The function works most of the time. If I choose Select All, it results in the proper response, " 'M 2S', 'M 2N', '4W', 'ICU', 'NICU', 'SNICU' ". IF I choose 'NICU', it results in 'NICU'. However, if I choose either '4W' or 'ICU', the result of the function is blank.

I created a small .fex file to highlight the issue. When I select 4W or ICU, the variable dummy shows '4W' or 'ICU' respectively. dummy2 is blank.

APP PATH ABSTRACTING NURSING
-SET &dummy = &SpecialCare.(OR(,,<4W,4W>,,,)).MultiLocationPrompt.;
-SET &before =''' OR ''';
-SET &after =''', ''';
-* STRREP(inlength, instring, searchlength,searchstring, replength,repstring, outlength, outstring)
-SET &dummy2 = STRREP(&dummy.LENGTH,&dummy, &before.LENGTH,&before, &after.LENGTH,&after, &dummy.LENGTH,'A&dummy.LENGTH');
-SET &ECHO=ALL;
TABLE FILE WF$HOLD
PRINT
&dummy AS 'dummy'
&dummy2 AS 'dummy2'
HEADING
""
FOOTING
""
ON TABLE SET PAGE-NUM OFF
ON TABLE NOTOTAL
ON TABLE PCHOLD FORMAT HTML
ON TABLE SET HTMLCSS ON
END

Tom,

I'm not sure if your example solves the problem. I think the auto-prompt causes a weird situation. If only one selection is made, the value of &dummy contains quotes. If the number of characters excluding the quotes is less than 4 (the number of characters in ' OR ') the STRREP function does not work.

The quickest solution might be to check the length of &dummy - if it's less than 4, most likely there's only one value, so don't use STRREP:

-SET &ECHO=ALL;

-SET &before = ''' OR ''';
-SET &after  = ''', ''';

-SET &dummy = &SpecialCare.(OR(<NICU,NICU>,<ICU,ICU>,<4W,4W>,<M 2S,M 2S>,<A,A>,<B,B>)).MultiLocationPrompt.;

-* STRREP(inlength, instring, searchlength, searchstring, replength, repstring, outlength, outstring)
-SET &dummy2 = IF &dummy.LENGTH LE 5 THEN &dummy ELSE 
-  STRREP(&dummy.LENGTH, &dummy, &before.LENGTH, &before, &after.LENGTH, &after, &dummy.LENGTH, 'A&dummy.LENGTH');

-? &dummy


(I hate auto-prompting)

Francis,

You are absolutely correct. I did miss the 1st line that checks for that, then, I concatenate the OR to it:
  
-SET &DUMMY = IF &DUMMY OMITS ' OR ' THEN &DUMMY  | ' OR ' ELSE &DUMMY ;


This way, the STRREP always works...

I was JUST focused on removing the quotes and the OR...

Good Catch!!! (3) lol

P.S. I, too, have disdain for the AUTOPROMPTER!!!! (4)

Me, three. I just talked a user out of deploying an app with the auto-prompt screen.

Obviously, we're all over 40! Roll Eyes

45??? (I am, been doing this(FOCUS) since '83) Razzer

My actual code in PROD:

  
-*************************************************************************************************
-IF &MAIN_SORT EQ ' ' GOTO SKIP_BYS;
-SET &MAIN_SORT = IF &MAIN_SORT OMITS ' OR ' THEN &MAIN_SORT | ' OR ' ELSE &MAIN_SORT;
-SET &SORT_LEN  = &MAIN_SORT.LENGTH;
-SET &KEY_SORT1 = STRREP(&SORT_LEN, &MAIN_SORT, 4, ' OR ', 1, ',', &SORT_LEN, 'A&SORT_LEN.EVAL');
-SET &KEY_SORT2 = STRREP(&SORT_LEN, &KEY_SORT1, 1, ''''  ,0,  'X', &SORT_LEN, 'A&SORT_LEN.EVAL');
-*************************************************************************************************

Thanks so much for all of your help! I really appreciate the quick responses! I incorporated your responses and it works great!

I had a few questions:
- What does this line of code do?
SET &KEY_SORT2 = STRREP(&SORT_LEN, &KEY_SORT1, 1, '''' ,0, 'X', &SORT_LEN, 'A&SORT_LEN.EVAL');

- Do you have any suggestions on how to build a SQL Report in Report Caster with multiple selections without using auto-prompter? I'm using that because I thought it was my only option for adding the data straight into the SQL statement

- For STRREP, is it always true that searchstring cannot be longer than the instring?

It is working wonderfully! Thank you!
