Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

If( Length(String_without_breaks)>0; 
 If( Left(String_with_breaks;1) = Left(String_without_breaks;1);
  Left(String_with_breaks;1) & 
  TrunctateStringWithBreaks( 
   Right( String_with_breaks ; Length ( String_with_breaks ) - 1 ); 
   Right( String_without_breaks ; Length ( String_without_breaks ) - 1 )
   );
  Left(String_with_breaks;1) & 
  TrunctateStringWithBreaks( 
    Right( String_with_breaks ; Length ( String_with_breaks ) - 1 ); 
    String_without_breaks)
  )
)

The script truncates the string_with_breaks at the position, then all values of String_without_breaks were shown in the correct succession.

There was an error in your coding. My test file did not like the TrunctateStringWithBreaks for this TruncateStringWithBreaks Note the difference in Trunctate and Trundate Also, When corrected, the String_without of 0014323 doesn't work, but 001 - 4323 does. Lee

My auto correct change the spelling of Trunctate to Trundate?

Hi, Just for fun, I do not test a lot, May be some results are not good, but, I would try this calculation, without recursive. Let ([ Val = "I just want to t-r-y, w i t h o u t recursion" ; VSearch = "trywith" ; Test = Left ( Filter ( Val ; VSearch ) ; Position ( Filter ( Val ; VSearch ) ; VSearch ; 1 ; 1 )-1 ) ; PosLeftS = Position ( Val ; Left ( VSearch ; 1 ) ; 1 ; PatternCount ( Test ; Left ( VSearch ; 1 ) ) + 1 ) ]; Middle ( Val ; PosLeftS ; Position ( Val ; Right ( VSearch ; 1 ) ; PosLeftS ; PatternCount ( VSearch ; Right ( VSearch; 1 ) ) ) - PosLeftS +1 )) result : t-r-y, w i t h Thanks for exercice ;)

PS : your cf is TruncateXXX but in your calc, you write TrunctateXXX ^ l
