Panels Status Values
The following is a list of values that can be returned in the status
field PPB-Status by a call to Panels.
Status Code Meaning
0 Function requested was successful.
1 The panel required does not exist. This value is
returned if you attempt to perform a function on a
panel that has not yet been created. You must
create a panel before it can be used.
2 The panel identifier is outside the range of valid
panel identifiers. The maximum number of panels
that can be visible at one time is 254. If you try
to enable more than this, a value of 2 is returned
in PPB-Status.
3 The update parameters supplied do not define
an area that is inside the panel. The
specified values of PPB-Update-Start-Row or
PPB-Update-Start-Col are outside the panel (that
is, they are greater than the height and/or width
of the panel).
4 The function number given in PPB-Function is not a
valid function number.
5 The program is trying to create too many panels.
The maximum number of panels have already been
created. This error will occur on a create
function if too many panels have already been
created.
6 The panel is too large. This value will be
returned on a create function if the program has
specified a panel size that is too large. Either:
a. The program is trying to create a panel that
is too large, that is:
PPB-Panel-Width * PPB-Panel-Height > 65535
b. The width of the panel is greater than 2000.
c. There is insufficient memory available to
hold the panel text and attribute buffers.
7 The value supplied in PPB-Scroll-Direction is not
in the range 0 to 3.
8 You are trying to scroll too many rows or columns.
The specified value of PPB-Scroll-Count is greater
than the number of rows or columns in the panel
(depending on the direction of scroll).
9 Panels cannot initialize. This is a fatal error
which occurs only on the first call to Panels made
by a program in your system. It means that for
some reason, Panels cannot initialize.
