Michael,
 
In a pinch, you could use the following SQL script to get your field info into 
table (file)yourlibr/RCD_LAYOUT:
 
DROP TABLE yourlibr/rcd_layout;  // do not do this the first time running the 
script!
 
CREATE TABLE yourlibr/rcd_layout
          (colno     DEC     (9,0) NOT NULL with default,
           sys_dname CHAR    (10)  NOT NULL with default,
           sys_tname CHAR    (10)  NOT NULL with default,
           sys_cname CHAR    (10)  NOT NULL with default,
           labeltext VARCHAR (50),
           length    DEC     (9,0) NOT NULL with default,
           coltype   VARCHAR (8)   NOT NULL with default,
           scale     DEC     (9,0),
           table_dsc CHAR    (50) NOT NULL with default,
           row_len   DEC     (9,0) NOT NULL with default,
           col_count DEC     (9,0) NOT NULL with default,
       PRIMARY KEY(sys_dname, sys_tname, colno));
 
INSERT INTO yourlibr/rcd_layout
   SELECT c.ordinal_position,
          c.system_table_schema,
          c.system_table_name,
          c.system_column_name,
          c.column_text,
          c.length,
          c.data_type,
          c.numeric_scale,
          t.table_text,
          t.row_length,
          t.column_count
     FROM syscolumns c JOIN systables t
       ON c.system_table_schema = c.system_table_schema
      AND c.system_table_name = c.system_table_name
    WHERE c.system_table_schema = 'your_library_name' 
      AND    c.system_table_name = 'your_file-name'
    ORDER BY c.system_table_name, c.ordinal_position;
 
Just put the above in a source member, then run the command:
RUNSQLSTM SRCFILE(srclibr/srcfile) SRCMBR(srcmbr) COMMIT(*NONE)
 
It works as a simple script as-is, or you can just use the SELECT in an 
SQLRPGLE program to manipulate programatically.  Using SQLRPGLE gives the 
advantage of using substitution variables to make it generic.
 
Regards,
 
William

Is there an API that can get me a list of fields in an externally-described 
file? Any program examples will be a great help. Thanks!
