Requirement:
1. File is openened and its content is picked up in an array IP_ARR
2. I only need the last record.

Is there any way to fetch the last record directly (apart from sequentially going thru the flat file and counting the number of records and then using the number to access the array something like IP_ARR.numofrec)?

Do you have an idea what stemvariable.0 contains? That should get you there.

  1. Rexx does not have arrays; it has stemmed variables.
  2. The question has nothing to do with arrays.
  3. As with all data sets, if the data set is DSORG=DA or is a RRDS, yes; if it is DSORG=PS or a ESDS, no (if it is DSORG=PO or a KSDS, the concept of "last record" is meaningless).

thanks Bill.
But I tried it already. and it's showing the stemvar.0,
although it is suppose to show the number of elements in the array.

OK. Typos can kill you in languages where you don't have to explicitly define the data :-)

  3. Hi, Opal!
I've "corrected" your post, Akatsukami! icon_smile.gif
