Reviewing a File
Tip11.scr, illustrated in Figure 126 on page 155, lets the user review the con-
tents of a file, one record at a time.
Figure 126. Tip11.scr Reviews a File
Copy: END Copies the constant “end” to the end of the default file to mark the last
record.
Copy: INDEX=1 Copies the number 1 into a register named
Index. This register will
determine which record is displayed.
Verify: END Looks at the record at the position specified in the
Index register. If the
record contains “end”, this is the last record in the file, and the program
deletes the “end” record and exits to the main frame. If it does not find
“end”, the program continues to the
Output node.
Output: INDEXED Displays the contents of the record at the position specified in the
Index register on the portable’s screen. Figure 127 on page 156 shows
the settings in the dialog box for the node.
