I have a little RPG challenge.
I get an 8 character string that has a number that may or may not have a
decimal position.
Examples: 12345.78 or 123 or 1.23456, etc.
I need to convert this to a number (10,5).
The way it was done in RPG prior was to move to an array and scan for the
decimal, do a bunch of move, movels.

Is there a more elegant way to do this in ILE?

I have done a similar thing with a bank file coming in,
here is a code snipit from a rather green, but willing pupil of ILE

in this example ================17 is being used because that is the
size of the input here, you would change that to 8
and since your number is  a 10/5 field,  lessthan  would 
be defined instead as            5  5
and   lessthandollar would be    5 


also the statement %subst(mwamount:pos:2) would have to be refined
to calc the end of the field so that 2 will also be a variable

This can at least give you some ideas of what you "could" do 


D wholenumber     S             17    
D wholenumbern    S             17  0 
D lessthandollar  S              2    
D lessthan        S              2  2 
D blankfield      S             17    
D len             S              5  0 
D blanklen        S              5  0 
D pos             S              5  0 

C                   eval      wholenumber    = *blanks     
C                   eval      lessthandollar = *blanks     
 *must find out what the field is, since comes in as alpha 
 *______check for the decimal position                     
C     '.'           scan      mwamount      pos            
C                   IF        pos = *zeros                 
C     ' '           scan      mwamount      pos            
C                   eval      lessthandollar = '00'        
C                   eval      len = pos -1                 
C                   eval      blanklen = 17 - len          
C                   eval      pos = pos + 1                
                                                           
C                   else                                   
                                                           
C                   eval      len = pos -1                 
C                   eval      blanklen = 17 - len          
C                   eval      pos = pos + 1                      
C                   eval      lessthandollar =                   
C                                          %subst(mwamount:pos:2)
C                   endIF                                        
                                                                 
C                   eval      pos = blanklen + 1                 
C                   eval      %subst(wholenumber:1:blanklen) =   
C                                %subst(blankfield:1:blanklen)   
C                   eval      %subst(wholenumber:pos:len) =      
C                                %subst(mwamount:1:len)          
                                                                 
c                   move      lessthandollarlessthan             
c                   move      wholenumber   wholenumbern         
                                                                 
C                   eval      BKCAMT =   wholenumbern  +         
c                                        lessthan                
                                                                 
where BKCAMT is the numeric field I am updating in a file from 

I don't know about elegance, but it works here...
