VarOpen
Declaration:
HSYM
VarOpen
(BYTE *
Types
{, BYTE *
subTypeList
[ ]})
Category(ies):
Dialog, Variables
Description:
Creates a standard OPEN dialog box (go to the Program Editor and do a
F1, 1 (Open . . . ) as an example). The user may select from a list of types
to open as well as the folder to look in and finally is presented with a
drop-down of symbols in the selected folder that are of the selected type.
Inputs:
Types
— An array, terminated by zero, of the following types:
GDB_VAR_TAG, PIC_VAR_TAG, TEXT_VAR_TAG,
DATA_VAR_TAG, MATRIX_TAG, LIST_TAG,
FUNC_BEGIN_TAG, PRGM_TAG, STR_DATA_TAG,
EQUATION_TAG, GEN_DATA_TAG. Each value in the
Types
list will be presented to the user in a drop-down
(unless there is only one value in the list then it will be a
static field).
subTypeList
(optional)
— For each GEN_DATA_TAG byte in the
Types
list, there
must be a string pointer in the
subTypeList
that points to
the text to display in the drop down. This parameter may
be left off if there are no GEN_DATA_TAGs in the
Types
list.
Outputs:
The HSYM of the selected symbol or H_NULL if the user presses
N
or
there is an error creating the symbol.
Assumptions:
None
Side Effects:
May cause heap compression.
The first WORD in the global array,
VarOptList
, is set to the index of the
type selected when
Types
contains multiple values. It will be one if the first
entry was selected, two for the second entry, and so on. See the example
below.
VarOptList
is available on AMS 2.00 and higher.
