REWIND

REWIND

Positions the table pointer at the beginning of a SAS table

Category: SAS Table

Syntax

sysrc=REWIND(table-id);

sysrc

contains the return code for the operation:

0	successful
0	not successful

Type: Numeric

table-id

is the identifier that was assigned when the table was opened in any mode except IS, US, or N. If table-id is invalid, the program halts.

Type: Numeric

After a call to REWIND, a call to FETCH reads the first row in the table.

If there is an active WHERE clause, REWIND moves the table pointer to the first row that satisfies the WHERE condition.

Call FETCHOBS to fetch the tenth row in the table MYDATA. Then call REWIND to return to the first row and fetch the first row:

dsid=open('mydata','i');
rc=fetchobs(dsid,10);
rc=rewind(dsid);
rc=fetch(dsid);
