Positioning The Current Line Pointer; Updating A Data Set - IBM System 360 User Manual

The FIND subcamnand starts looking for the sequence of characters
beginning with the line at which the pointer. is located.. Therefore,
unless you are sure the characters are in a line following the one
indicated by the
pointer~
you should use the TOP subcommand to move the
pointer to the beginning of the data set. For example:
top
find xplaced before entry
Figure 6 shows a data set used to illustrate the examples of
positioning the current line pointer. Although this data set has line
numbers" they are not used in the examples.
