(b) Enter the x-axis scale factor to en-
able the graph to be ‘stretched’ on the x-
axis to observe cramped points properly.
After entering the x-axis scale, the graph
appears along with all relevant data, like
scale factors for x and y axis, file name,
Program Listing for SPEEDM.CPP
and units, etc.
(c) While still in the graph mode, you
may view a new graph after pressing F1.
For returning to the main menu, press
F2.
3. Help. This module provides one
page of help and reads from a file called
HELPS.PG1. If this file cannot be opened,
or is not available, the software prompts
with “Help file not found or cannot be
opened.” Pressing any key from the help
page returns one to main menu. The con-
tents of HELPS.PG1 are given in the box
(on previous page).
