To update members of a PDS, by comparing values with PS file

Postby Akshata » Tue Feb 26, 2019 12:09 am

I am trying to change the password value present every member of a PDS, with the new password value present in a PS file(by comparing Username value).
PDS members:

Member1:

Member2:
Image

Member3:
Image

PS file:
Image


Updated members of the PDS should look like below:

Member1:
Image

Member2:
Image

Member3:
Image


Note:
• There is no specific length defined for any values present in PDS/PS file, only User name value can be used to compare.
• Only password value needs to be changed in each PDS member
• There nearly 500 members to be updated as part of this change.

Please suggest the way to perform this change.

Thanks in advance.

First, you need to read the password file and separate the two blank delimited tokens so that you have the search-string in one variable and the password in another variable. Because there seems to be at least three userids involved, use a stem variable to keep track of the userid / password values.

Second, process each FTP member, one at a time, as follows:
a. read the member into a stem variable.
b. process each line of the stem variable, looking for each search-string in column 1.
c. when you find a match:
c1. replace the password in FTP stem variable
c2. write out the FTP stem variable to replace the member.

I mentioned stem variables twice... there should be two different stem variables.

a solution with an ISPF edit macro might be simpler

that' s the reason I moved the original topic to the TSO & ISPF section

ad find extracting the line number would be much simpler than
process each line of the stem variable, looking for each search-string in column 1.

Completely off-topic, but 500 passwords in plain text?

It's about time your auditors start making sure a few people get pink slips or the Indian equivalents!!!
