Re: %Len vs. %Size in %Replace

I'm on v5r1 and they both work for me with your code. 

The only problems I see is when your 

"%Scan( 'qqqqqqqqqq': String ) :" dosen't get a hit on anything you get "The 
target for a numeric operation is too small to hold the result" 

or if you change "D String  80A" to be varying you get the following on 
both "Length or start position is out of range for the string operation." when 
no hit on %scan. 

One problem with %size is that you will replace 12 positions in String 
with blanks if "Objectname" has nothing with %len you will do nothing 
because it will return 0. 


Test Code as follows. 

I would play with it so you can see your own results.I would look at Pos / 
Siz / Len to see the numbers with different data. 
 

D ObjectName      S             10A   VARYING 
D String          S             80A   VARYING 
D                                     INZ('1234567890qqqqqqqqqq12345')
D Scanwith        S             10A   INZ('qqqqqqqqqq') 
D Pos             S              5U 0 
D Siz             S              5U 0 
D Len             S              5U 0 
 
C                   Eval      Pos    = %Scan(Scanwith:String) 
C                   Eval      Siz    = %size(ObjectName) 
C                   EVAL      String = %Replace(ObjectName:String: 
C                                       Pos:Siz) 
 * Reset for test 
C                   Eval      String = '1234567890qqqqqqqqqq12345' 
 
C                   Eval      Pos    = %Scan(Scanwith:String) 
C                   Eval      Len    = %len(ObjectName) 
C                   EVAL      String = %Replace(ObjectName:String:
C                                       Pos:Len) 
C                   Eval      *Inlr  = *on 


Hope this helps

Hans,

  This is targeted to 5.1.  It is for a fixed length variable and the only 

change I made to the code was to switch from %Size() to %Len().  Any other 

ideas?
