Using detectable fields

When CICS® generates an HTML page from the 3270 data stream, it simulates detectable fields with a text input field preceded by a check box.

Attention: This topic contains Product-sensitive Programming Interface and Associated Guidance Information.

To use detectable fields, the bridge facility associated with the transaction must be configured. Enabling detectable fields tells you how to do this.

Detectable fields are those in which:
  • The field attribute byte identifies the field as being detectable or intensified.
  • and The first character of the 3270 field contains a valid designator character. This can be an ampersand (&), a right angle bracket (>), a question mark (?), a blank, or a null.
For more information about detectable fields, see the CICS Application Programming Guide.
When the check box and text input field are displayed on the Web client:
  • The designator character in the 3270 field is not displayed. Accordingly, the field length in the Web client is one character shorter than it is in the 3270 datastream.
  • If the designator character is a right angle bracket (>), the check box contains a check symbol (✓). Otherwise, the check box is empty.

To use the detectable field on the Web client:
