Converting VARCHAR fields

Hi,
      I have an SQLRPGLE program that has a VARCHAR field as an input parm.
I am having trouble converting it to an alpha field.  This is the relevant
code I have.

H OPTION(*NODEBUGIO: *SRCSTMT) CVTOPT(*DATETIME:*VARCHAR)
D InEmp              S             25A   Varying
D WkEmp           S             25
D                 DS
D String                  1    255A   VARYING
D  Length               1      4B 0
D  Data                   3    255
D*
C                   EVAL      String = InEmp
C                   EVAL      WkEmp = Data

When I put in debug, after the last EVAL, WkEmp still has the length at the
beginning of the field. I shows up as a green block 2 spaces wide, then my
value.  What am I doing wrong?
