Hi,

I wanted to pass parameters to a easytrieve program through the JCL, just the way we do PARM in cobol , I am not even sure if this is possible.
It would be very helpful if i could get some ideas on this.

Thanks a lot,

Chandu,

What exactly do you want to pass? Please let us know the exact requirement and may be we can suggest an alternate solution.

Hi Kolusu,

Sorry for not posting the entire details ,
I wanted to pass dates in the parm , The dates would be the starting date of the month and the other date would be end date,
like start date could be 20040501 and end date could be 20040730, The processing would be dependent on the date range.
Firstly i wanted to know if passing Parm is an option in Easytrieve,
The only other option i have is to take a file and in that pass data.

Thanks a lot,

Chandu,

Unfortunately eztrieve does not let you pass parms. But you can pass them via file and read the file just once and move them to a working storage variable and use them for validation.

Thanks a lot Kolusu,
I have used it the way you demonstarted and it works great.

Regards,
Chandu

Chandu,

Eztrieve does allow for processing of a parameter coded on the execute statement. See the utility program EZTPX01, the following is a brief description from the manual.

Utility Programs
EZTPX01
EZTPX01 is a called subprogram used to interrogate a PARM coded on a JCL
EXEC statement. It is distributed with CA-Easytrieve Plus.
EZTPX01 requires two parameters, the system defined PARM-REGISTER, and a
user defined input/output field. The input/output field must consist of a 2-byte
binary field immediately followed by a character portion to contain the actual
PARM information.
You are responsible for placing the maximum length you expect for the PARM
information (the character portion) into the 2-byte binary field before calling
EZTPX01. EZTPX01 moves your PARM data from your JCL EXEC statement into
the character portion of your input/output field and updates the length in the 2-
byte binary portion.

If the PARM data is larger than the maximum length you specified, it is truncated
on the right and the maximum length you defined is retained. If the PARM data
is shorter than the length you specified, the length is updated to reflect the actual
length of the PARM data. See the “Processing JCL Parameters” chapter in the
CA-Easytrieve Plus Application Guide for a sample program using EZTPX01.

==>> I have used this and it works quite nicely. but I still prefer Cobol...

Chandu,

I am sorry for telling that easytrieve does not have the option of passing parms. I haven't used them till date.

Chuck thanks for the valuable piece of information. upon looking at it is quite similar to the START procedure I used.

I will try to run the example shown in the application programming guide.

Thanks

Kolusu

Thanks Kolusu
Thanks Chuck

I tried the example given in the Application program guide and it works pretty nicely even for PARM's greater than 10 bytes
This thing was an eye opener for me regarding utility programs.

Thanks a lot,

Regards,
Chandu

Chandu,
Here is how can pass parameters is Easytrieve Program. I know it is too late but still in case if you need in future.

1) Create a Member EZTPARM with following code
