Hi,

I have a field that holds a string of data separated by a semi-colon ';'.  I need to split this string between 1 and 5 fields.  Once the string is split I will need to show each field that contains data in the report.  

Example of the strings:

Accelerations; Early
Accelerations; Early; Late
Accelerations; Early; Late; Recurrent
Early; Late; Variable; Recurrent

I want to display the split fields as:  
Field 1                                   Field 2                      Field 3                 Field 4
Accelerations                       Early                        
Accelerations                       Early                         Late                      
Accelerations                       Early                         Late                     Recurrent
Early                                      Late                          Variable              Recurrent

What is your database ?
The best way to handle this is on database side.
Here is an example hot to do this with SQLServer

You may also use SQLExpressions to get each part of the string

You can use SPLIT to separate them into an array

HOw many might there be?

Formulas to do this
Formula1 - Name - DispField1
WhilePrintingRecords;
Global StringVar Array myStrings;

myStrings:= Split({YourField},';');
If UBound(myStrings) >= 1 then
     myStrings[1]

Open in new window


One formula for each string - Just change the 2 to 3, 4, 5, etc

Formula2 - Name - DispField2
WhilePrintingRecords;
Global StringVar Array myStrings;

If UBound(myStrings) >= 2 then
     myStrings[2]

Open in new window

If you use formulas like the ones that mlmcc posted, you would also want to add the following line to the beginning of every formula except the first one:

 EvaluateAfter ({@DispField1});

 That's to make sure that each of the other formulas is evaluated after DispField1, because it sets the myStrings variable, and the other formulas get their values from myStrings.
