var
[
,alphaOn/Off
]
If Request is inside a Dialog...EndDlog construct, it
creates an input box for the user to type in data. If it
is a stand-alone instruction, it creates a dialog box
for this input. In either case, if var contains a string,
it is displayed and highlighted in the input box as a
default choice. promptString must be
{
20
characters.
This instruction can be stand-alone or part of a
dialog construct.
Request "Enter text",t,1
¸
The argument turned on alpha-lock in the
above example.
The optional alphaOn/Off argument can be any
expression. If it evaluates to zero, alpha-lock is set
to OFF. If it evaluates to anything other than zero,
alpha-lock is set to ON. If the optional argument is
not used, alpha-lock defaults to ON.
If more than one Request command appears within
a Dialog...EndDlog construct, the first alpha setting
is used and subsequent ones are ignored.
Request “Enter number”,n,0
The argument turned off alpha-lock in the
above example.
