Re: Help improve performance of RPG program - Long Post

Rich,

Rather than do everything dynamically in this program have the program
generate RPGLE, SQLRPGLE or SQL source code to do the actual conversion.
Your main RPG program writes and then compiles a specific RPG program to do
the actual conversion.  The generated code wouldn't have to work through
arrays and would be faster.  If you generate RPGLE code you could avoid
using SQL entirely.

Or you could go the other way and have your main RPG program write and then
run SQL source.  In this setup your date conversion routine would be a SQL
user defined function executed by the generated SQL source.  You could get
away from having to process the SQL a record at a time in your main program.
One INSERT statement for the file header record (or maybe the main RPG
program writes this record directly).  Another INSERT statement for the
field/column names record (or maybe the main RPG program could continue to
write this record directly).  Then a third INSERT using SELECT for the
remainder of the file:

INSERT INTO FTPOUTPUT ( FTPFIELD ) SELECT RTRIM( TEXT) || ',' ||
MYDATE(DATE) || ',' || CHAR(NUMBER) [etc] FROM INFILE
