The row and column coordinates on a terminal screen. See the status
bar at the bottom of the terminal screen for the offset value of the
cursor position.
The offset is zero-based and is the equivalent of the following formula:
offset = [(row - 1) x width] + (col - 1)
The reverse formulas (offset to row/col) are as follows:
row = (offset / width) + 1, where the division operation uses integer
logic (remainder of the division operation is ignored)
col = (offset % width) + 1, where % means modulo (use only the remainder
of a division operation)
Example: For an 80-column terminal screen:
row 1, col 1 = offset zero (always true)
row 1, col 2 = offset 1 (always true)
row 2, col 1 = offset 80 *(depends on the screen width)

| Echo |
If you are modeling a block
mode application, select the Don't wait for echo option. If you
are modeling a character
mode application, select from the following options:
- Don't wait for echo (Default)—Select this option to transmit
the string to the host and immediately move to the next action. Always
use this option for block mode applications. For character mode applications,
use this option only when you know that data will not be echoed
back to the terminal screen. For example, many times alphanumeric keys
are used to move between screens and are not echoed.
- Wait for next tabstop—Select this option to wait for the
cursor to appear at the next tabstop after transmitting data. If tabstops
have been defined on the Cursor tab,
then Host Integrator waits for the cursor to appear at one of the defined locations.
If no tabstop definitions are applicable, then Host Integrator waits for the cursor
to be anywhere on the screen that is outside the attribute or recordset
field to which the data is being written.
- Wait for next tabstop or string to echo at cursor—Select
this option to wait for the exact data string to be written back
to the terminal screen or to wait for it to appear at the next appropriate
tabstop. This option is not recommended.
- Wait for same number of characters to echo—Select this
option to wait for the same number of characters to be sent back to
the terminal screen after data has been transmitted to the host. To
detect the number of echoed characters, Host Integrator transmits the
data and waits for the cursor position to move the same number of columns
as the length of the data transmitted. For example, if you transmit
the name George as your password, a host will often echo six spaces
instead of the original text. With this option selected, Host Integrator
waits for the cursor to move six columns from the cursor position when
the name George was transmitted to the host before moving on to the
next command.
- Wait for string to echo at cursor—Select this option
to wait for the exact data string to be written back to the terminal
screen after data has been sent to the host. This is the most robust
option to select when working with character mode hosts. Note:
With character mode applications, the cursor must be wherever characters
are being written to the screen. For this reason, use this option to
synchronize with the host application.
- Wait for cursor to arrive at specific location—Select
this option to wait for the cursor to arrive at a specified location.
