Q:Hi all,i want accurate answer with code using in built
functions.please sent me code as soon as posible.
I have program nmed PGM1 which '' RETRIEVE Current
production date''should correctly default the production
date for the user who is issuing raw materials to the
manufacturing.The production date can be different from the
celendra date.
However, the program does not make the correct adjustment
for all manufacturing plants.
there is a parameter which determines the
production start time e.g. 07:00 if the system time
precedes this,the program subtracts one from the celendra
day.This work fine when the celendar day starts after
production day as it does in England,the system should be
adding one to the celendar day during the overlap.
unfortunately the program was desined to assumed the
celendar day always starts before the production day.
Change required in the program:
Change the
PROGRAM PGM1 to use the new parrameter to decide whether to
add or subtract 1 from the celendar day when determining
the production date.
i have two flat files.i want to select one record from that
file by using jcl.for example file1 contains emp
no,name,joining date. file2 has same details.emp no is
primary key. i will give empno.that emp details send to
outfile.please let me know if any one knows it.give sample
code.
SET is the ANSI standard for variable assignment, SELECT is
not.
SET can only assign one variable at a time, SELECT can make
multiple assignments at once.
If assigning from a query, SET can only assign a scalar
value. If the query returns multiple values/rows then SET
will raise an error. SELECT will assign one of the values
to the variable and hide the fact that multiple values were
returned (so you'd likely never know why something was
going wrong elsewhere - have fun troubleshooting that one)
When assigning from a query if there is no value returned
then SET will assign NULL, where SELECT will not make the
assignment at all (so the variable will not be changed from
it's previous value)
As far as speed differences - there are no direct
differences between SET and SELECT. However SELECT's
ability to make multiple assignments in one shot does give
it a slight speed advantage over SET.

Please tell me how to read the records from a file with
load an array of size with error conditions(The logic
answer for this question is ARR is array of 99 elements
Z-ADD 0 IDX
*LOVAL SETLL FILE
READ FILE 99
*IN99 DOWEQ *OFF
IDX ANDLT 99
ADD 1 IDX
MOVE FIELD ARR,IDX
READ FILE 99
ENDDO).So,Please give me the complete of this code.

RETRIVING DELETED RECORDS :-
I'm frequently asked how to retrieve deleted records from
an unjournaled physical file when the deleted records have
not yet been removed from the file.
Utility UNDEL lets you undelete records in a physical file.
This public domain program is available in CISC and RISC
versions, and the complete source code is available for
download at:
UNDEL for AS/400 Save File (RISC):
http://www.as400network.com/sharewarefiles/undelris.zip
UNDEL for AS/400 Save File (CISC):
http://www.as400network.com/sharewarefiles/undel.zip
UNDEL for AS/400 Save File (Source code):
http://www.as400network.com/sharewarefiles/undelsrc.zip
The utility takes advantage of the fact that deleted
records in physical files are only flagged as deleted, and
the record data still exists until it is overwritten or the
file is reorganized with a utility such as RGZPFM. UNDEL
simply reads the deleted record, then reuses the record by
writing over it with the new record (thus eliminating the
flag for the deleted record).
Some homegrown and commercial utilities copy the file
containing undeleted records to a save file, then use a
program to read the save file, which contains live and
undeleted records, to a file to undelete the records. The
UNDEL utility is superior to the SAVF technique because
there's no need to copy the file to a save file, which is
especially important for really large files.
When run, UNDEL displays the physical file records in their
unformatted, raw text form. You can either position the
display to a given relative record number or use F19 or F20
to find the previous and next deleted record, respectively.
The utility also includes online help, which is almost
unheard of for free utilities.
Other utilities include the ability to undelete records.
You can use the RTVDLTRCD command in the old QUSRTOOL (no
longer supported by IBM). QUSRTOOL is now a commercial
product called TAA Productivity Tools (
http://www.taatool.com ). The free file editor WRKDBF has a
built-in undelete capability ( http://www.wrkdbf.com ), and
several commercial file editors can undelete records. For a
complete list of file editors, go to
http://www.sourcebook400.com, select "Programmer Tools"
under "Product Category," then select "File Editors."
Can any one tell me that how we go for the compare,unit
testing after changing requirement as per client request.
this is very helpful for me when u give suitable (coading)
exmple.
