how to read only a particular record from a file using rexx

superk

You can start by reviewing the EXECIO command.

You need to be more specific about what you mean by "a particular record". Do you mean a particular record number?

Hey N.SUDHA,
You should not post another doubt in the same forum. Its become tough to correlate. However what SUPERK has said is quite fine. For move you can put those two records in a stem and free the DS. Then again use ALLOC in MOD mode. and use EXECIO DISKW to write the records in the particular position.

You also can use macro and read upto the record you want(Eg;- upto 9th record). Now place the 9th record & 10th record in the stem. Now you want to place that records (say - 3 & 4th position), then again place the cursor at the first position and read upto 2nd position and put the records in the 3rd & 4th position.
