1)How to extract 41 to 45 portion from a variable which is declared as

Hey U can use the refrence modification or the Unstring command to extract the 41 to 45 portion of a variable ie,
Move x(41:5) to new-varaibale-name;

2) How static call and dynamic call works when changes are made both
in main pgm and sub pgm?

Check the link www.screenio.com/tips/calls.htm

3) sHOW YOU can arrange the following in sorted order using search(2,5,1,3...)?
U mean to arrange the following numbers in the sorted order or u mean to search a particular Number.
If u use binary search the Numbers shuld be sorted b4 the search can be performed

4) If 100 pds members are there how can you locate nameof particular pds?
Use the locate comand it should work fine

Q : If 100 pds members are there how can you locate nameof particular pds?

ANS :You can also use Search in dataset utilities. 3.14 or 3.15 option by which you can search for a particular string or strings in a PDS. The string can be anything Member name, Program name inside a member.

Q : how we can convert 9(10)v9(2) to 9(12)v9(2)?
ANS : You can redefine it with 9(12)v9(2).

Correct me if I am wrong.

Thanks & Regards,
Ranjit...
