There is no such thing as a point-and-shoot field in the 3270 data stream. There are selector-pen detectable fields and fields with triggers, but neither provides a protected field that you can tab into.

Does 3270 protocol require that PAS fields be writable, therefore tabbable? Bad design. It's perfectly reasonable to want to specify a read-only PAS menu item. (Too few bits in the attribute byte?) I believe many emulators nowadays interpret double-click as "shoot". Or provide "shoot" as a pop-up selection. Long ago, I tried to specify a single-cell PAS field. The host application rejected this, claiming that a light pen can not resolve a single cell. Bad Lowest Common Denominator design. The application should support a possibly hi-res light pen or other PAS device. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
