Re: output date field from a flat file into a variable

I am hoping there must be a way to get 1. by using SQL(as written in my earlier email) in CL, that is what  I am looking for...

1. I am assuming that you are getting the first variable from an RPG
program or HLL language as CL doesn't run SQL directly and that you must be
calling a CL program passing that value as a parameter defined as 8 *CHAR
and the second variable is defined in the CL as 8 *CHAR also.

So you code already says it already.

If (&VAR *EQ &DATE) DO
,,,
If (&VAR *LT &DATE) DO
...
If (&VAR *GT &DATE) DO

If you have a relatively modern OS you can do
SELECT
  WHEN (&VAR *EQ &DATE)  THEN
    ..
  WHEN (&VAR *LT &DATE)  THEN
  ...    ...
  WHEN (&VAR *LT &DATE) THEN
    ...
ENDSELECT

Am I missing somthing?

1.I can get the date(&var) by using SQL given below (SELECT
substr(admadmrec, 9,8)from admfile)

2.I get the date (&date) from an application by using RTVxxxxx command
output to variable &date.

3. I need to compare them both in CL and do some further steps.

If I am understanding your question correctly, why do you need to do
anything. Both field are in a CCYYMMDD format and are character fields so
just compare them unless you are saying that the field &DATE is a true date
type type from database table? CL doesn't support true date data types.

Hi

I am looking to do date comparison in CL program.

    I get the date from a flat file with the below SQL
SELECT
      substr(admadmrec, 9,8)
from admfile

the value is in format yyyymmdd.

  How do you  output this date into a variable (&VAR) to compare with
another variable(&DATE) that picks APPLICATION DATE in the same format
20130608(yyyymmdd).


Below is the structure of my CL
PGM
DCL &VAR
DCL &DATE

-----
-----


IF &VAR = &DATE
DO --------
IF &VAR < &DATE
DO ---------
IF &VAR > &DATE
DO --------

ENDPGM

Thanks!
