RE: menu choice - scalcout?

["Mooney, Tim M." <mooney@aps.anl.gov>]

You could do this is with an mbbo record followed by an scalcout record.  If the text strings are all shorter than 16 bytes, the mbbo record could hold the text strings in a form that EDM and other display managers already know how to display as a menu.  The mbbo record's forward link would process the scalcout record.  The scalcout record's INPA link would read from the mbbo record's RVAL field.  The scalcout record's INAA, INBB, INCC, etc. links would read from the mbbo record's ZRST, ONST, TWST, etc. fields, respectively.  The scalcout record's calc _expression_ would be "@@A"; this _expression_ tells the scalcout record to use the AA field if A==0, the BB field if A==1, the CC field if A==2, etc.

If the text strings are longer than 15 bytes but shorter than 40 bytes, you could do something similar.  The mbbo record string fields would not contain exactly the strings to be sent, but only abbreviated versions for the user to choose from.  The actual strings to be sent would be hard coded in the scalcout record's STRn fields, instead of being read from the mbbo record's string fields.

If there are more than 16 strings, you could use an mbbo/scalcout pair for each set of 16 strings, and they would have to be on separate menu buttons in the EDM display.

Subject: menu choice - scalcout?

I would like to be able to use a radio box or menu button in EDM to send one of a pre-defined set of text strings to a record.  How would I do this?  Somehow modify scalcout to include a menu of choices?

Thanks
