Nortel Networks VT100 manual Screen-name, Validation-tag offset

2-18Template files

#comment

The first line of the template in Figure 2-12 is a comment. The comment line is not required but is recommended to describe the purpose of the screen template.

Comments can be embedded anywhere in the screen template and start with the “#” symbol. If a comment begins a line, no non-comment fields may follow the comment. However, a comment may appear after a non-comment field, such as after the field descriptor line shown in Figure 2-12. It is good programming practice to heavily comment files.

screen-name

The first non-comment line specifies the name of the screen. This is the screen template file name without the .scn extension.

validation-tag offset

This entry specifies the position of the validation-tagby row and column. You may enter 0,0 for the validation-tag offset in only two cases:

•To indicate that you do not want to validate this screen (you would also need to enter a hyphen, “-”, as the validation-tag). You should only ignore the identity of a screen if you want the TRS process to perform the actions specified in the screen template regardless of what screen is actually active. For example, if you want to execute a command at the system prompt, you would not need to verify that you are at a specific screen, as long as you are sure the screen has a system prompt.

Note: In general, you should validate screens whenever possible. This ensures data for the host computer application is sent to the correct screen, and data sent back to the Meridian IVR 2.0/I application is from the correct screen.

•To tell the TRS to search the screen for the validation tag. If you do not know the exact location of the validation tag or if the location of the validation varies, you can tell the TRS to search the screen for the tag. Enter 0,0 for the offset, then enter the validation tag in the appropriate field.
