%Trim

[Rob Berendt <rob@xxxxxxxxx>]

Has anyone noticed how slowwww that %Trim is?   Create an ILE RPG program with 
a alpha variable of 32,767 bytes long.  Perform a %Trim operation on that 
field.  Run it in debug.

Another thing I've noticed.  There are times when you would think that a %Trim 
should work when you should be using a %TrimR.  For example
DRecipientDS      DS                                                   
D  RecOffSet              1      4B 0 INZ(0)                           
D  AddrLen                5      8B 0 INZ(0)                           
D  Format                 9     16    INZ('ADDR0100')                  
D  DistrType             17     20B 0 INZ(0)                           
D  Reserved              21     24B 0 INZ(0)                           
D  Recipient                         Like(RecAddr) INZ('rob@dekko.com')
C                   Eval      RecOffSet = %Len(%Trim(RecipientDS))
 * In the above RecOffSet will be equal to 29 because the first two subfields 
will be dropped.
* In the following RecOffSet will be equal to 37.
C                   Eval      RecOffSet = %Len(%TrimR(RecipientDS))
