Rexx Gurus,
As per my requirement i would get the column no and the data as inputs and i should update the record with the data in that particular column.
say for example the input data that i get is
column - 15
data - Aaru
then i should update all the records with "Aaru" starting from column no 15. Is there any function in REXX to do this? |

I think there is a possibility that data in other columns will make POS difficult to use.
For example, say the search was for aaru in column 15 and data was:
| Code: |
----+----1----+----2---
aaru aaru aaru |
if POS('aaru', whole_line) = 15 ...
would give false results.
perhaps:
| Code: |
column =15
serch = 'aaru'
If substr(whole_line, column, length(serch) = serch then... |

Hello,
I may misunderstand the requirement, but my understanding is that the user will provide a starting position and a "fill" value. The code should fill all of the records with specified value at the starting position. |

I have used POS before, and to my knowledge it can be used for finding the starting position of the string.

Exactly. You are correct and that is what my requirement is. |

charan,
First of all your requirement is different from mine and it is doable.

Use POS u can get the column no/position where the accounting info starts[by checking for "("] and based on that u can edit the data. |

here is a snippet that will parse a job card for accounting data
get rid of the old account info,
rebuild the same card with the new account info
| Code: |
jobcard = " //jobname JOB (sccnt,wwww,qqq),class=a, "
jobcard = " //jobname JOB acct,class=b, "
jobcard = " //jobname JOB (sccnt,wwww,qqq),class=a, "
jobcard = strip(jobcard)
p = pos("JOB",jobcard)
jhead = strip(substr(jobcard,1,p-1))
if p = 0 then do
say "not a JOB stmt :" jobcard
exit
end
data = strip(substr(jobcard,p+4))
say "data " data
if substr(data,1,1) = "(" then do
p = Pos(")",data)
acctinfo = substr(data,2, p-2)
jtail = substr(data,p+1)
end
else do
p = pos(",",data)
acctinfo = substr(data,1,p-1)
jtail = substr(data,p)
end
say "jhead " jhead
say "jtail " jtail
say "acctinfo" acctinfo
parse var acctinfo acct1 "," acct2 "," acct3 "," acct4 "," .
say "acct1 " acct1
say "acct2 " acct2
say "acct3 " acct3
say "acct4 " acct4
newacct= "(new,acct.info)"
jobcnew = jhead || " JOB " || newacct || jtail
say "jobcnew " jobcnew

Did you try OVERLAY function.
e.g.
OVERLAY(' ','abcdef',3) -> 'ab def'
OVERLAY('.','abcdef',3,2) -> 'ab. ef'
OVERLAY('qq','abcd') -> 'qqcd'
OVERLAY('qq','abcd',4) -> 'abcqq'
OVERLAY('123','abc',5,6,'+') -> 'abc+123+++'

regarding Aaru's original requirement:
> i should update all the records with "Aaru" starting from column no 15
A. I understood it to describe a filter:
i should update all the records THAT HAVE "Aaru" starting from column no 15
B. whereas, Dick understood it to mean:
i should update all the records AND REPLACE ANY TEXT IN COLUMN 15 WITH "Aaru"
If it really is B, then I do not understand how POS can help. |

You are correct and POS cannot be used for the same. This has already been said in the previous post. |

Basically my requirement is to get few column no's/data from the user and update that particular column in a PS/VSAM files with the data.
first i want it to implement for PS/alphanumeric/numeric fields and then extend it to VSAM/COMP/COMP-3 fields and all
i have not written any macro's and have to dig a bit to see if i can use it. I shall give it a try.
Thanks for your valuable suggestions. |

I doubt that you will be able to use similar methods to update both PS and VSAM files. |

Hmm even i doubt. My first task is to make it work for a normal sequential dataset and then should try for VSAM. |
