Table 2-1
Valid field I/O entries
Note: Place the asterisk and dollar sign characters in quotation marks if your
field-descriptors require their use without their associated buffer commands.
For retrieving data into an output buffer, $num indicates the number of
characters to be retrieved from the field; using $ without a number retrieves
characters until an attribute is encountered, or a maximum of 31 characters
have been retrieved.
Internal variables (indicated by the % symbol) are used within the VT100
screens only and cannot be transmitted through the TRS gateway. You can
only use internal variables to store and enter data from one screen to another
in the host computer application. To send the data to the Meridian IVR 2.0/I
application that called the TRS process, you need to store the data in an output
buffer.
Entry Description
* Inputs the contents of the next input buffer (transmitted
from the Meridian IVR 2.0/I application) into the field
and used for COMI cells.
$num Outputs the contents of the field into the next output
buffer. num is a number in the range 1-31 and
represents the number of characters in the field TRS will
put in the output buffer. If you do not assign num a
value, TRS will place 31 characters into the buffer. It is
used for COMO cells.
%n$ Outputs the contents of the field into an internal variable
named n, which must be a number from 1–9.
%n* Enters the contents of internal variable n into the field.
%n$num Outputs the first num characters of the field into variable
n.
text Any text string to be entered in the field. If any of the
special characters listed in this table are to entered as
text, enclose the entire text in quotes (e.g., “$abc”).
BLANKOUT Clears TRS memory space associated with the host
application screen before retrieving output.
