Input fields With the switches /e and /i you can assign input fields to the variables:
/e: shows the current value that can be overwritten.
/i: shows an empty field in which a new value can be entered.
In addition, both switches /e and /i can be given an identifier xxx ( /e = xxx ,
/i = xxx
), where
xxx
is a positive whole number. With Module 9211 you can
then ascertain whether the cursor is located in this field.
With the /s = xxx switch a field is produced in which no input is possible. By
entering the identifier
xxx
it is possible to ascertain with Module 9211 whether
the cursor is located in this field.
If the switches /e , /i or /s are used, the cursor keys function as jump
commands from input field to input field. If necessary the current page is
scrolled. Text between the input fields may no longer be displayable.
The C command “printf” requires a format that defines the length of the
numerical field:
7 7 7 7 Save this format in the mask file. Otherwise the length of the input field
depends on the coincidental content of the associated variable.
For the input function this format instruction is converted internally into a form
suitable for the C command “scanf”:
printf:
%[flags] [digits1] [.[digits2]] [1] conversion_char
scanf
: %[digits1] [size] conversion_char
Note
Do not edit any text before the first input field or after the last.
Note
Special characteristics
n
%d, %e
The size information “1” can be omitted. Floating-point variables are of
the double type and automatically add to this information.
n
%g
Do not use. Causes errors.
n
%i
Do not use. Any number entered with leading zeros would be interpreted
as an octal number.
n
%u
Works correctly only in the definition range for the respective variables.
n
The size indicator
h
(short integer) of the ”scanf” function cannot be
written. All integer variables are automatically expanded to 32 bits for
input and output.
