It is possible to accept a form without user confirmation using Form attribute No Confirm.
For example :
[Form: TSPL FFE Sample Frm]
No Confirm: Yes
Also, if Report Attribute Auto is enabled, automatically the Form does not prompt for user confirmation. Report Attribute Auto is generally used in Configuration Reports where changes in the variable is intended to alter the variables associated with the parent report and hence, an Auto Report cannot have variable association within itself.
