3082.0. "Need help with RECOG form" by SWAM2::RHODEWALT_BR (I am a talking parrot.) Wed Jul 28 1993 17:02

    Is anyone using RECOG forms? Are they documented anywhere besides
    Redmond II?
    
    I tried to change recognition on a field from /RSE_RECOG to
    /USE_FORM="form_name" and the form broke. When I attempt recognition I
    get a message that says "Form DMA_MASTER is not in the library."
    (DMA_MASTER is the data set we're recognizing against.)
    
    Old:
    
    ;;PICTURE;;
    /RSE_RECOG=DMA_MASTER WITH...
    
    New: 
    
    ;;PICTURE;;
    /RSE_RECOG=DMA_MASTER WITH...
    /USE_FORM="DMA_INFO_RECOG"
    
    I've checked for missing fields. The recognition form has ND directly
    copied from Redmond II. DMA_INFO_RECOG produces no errors when I call
    it interactively. (Doesn't display, either, but that's okay.)
    
    Thanks for any help.

3082.1Sorry - my mistake...IOSG::CHINNICKgone walkaboutFri Jul 30 1993 11:3937
    Bruce,
    
    To be precise, ALL-IN-1 uses:
    
    	FORM <string>
    
    to invoke a "Recog" form i.e. any form and qualifiers you like.
    
    and
    
    	FORM <name> SELECT/FIELD=DISPLAY/OVERLAY
    
    for an ordinary select form.
    
    When it returns from either type of invokation, a CLOSE_PRIOR is
    performed and any select context is cleaned up. Then, if OA$SEL_COUNT
    is zero the recognition fails. If OA$SEL_DISPOSE indicates an EXIT then
    no message is signalled. If OA$SRC_COUNT is zero then you get the
    message "No item satisfied the search criteria" otherwise "No item was
    selected". 
    
    Before the "Recog" form is invoked, the SELECT context is set up using
    the RSE from /RSE_RECOG as well as other qualifiers like /UNIQUE and
    /SHOW. The %KEY field, DSAB field specified or /SHOW information is
    used to generate a SEL_CHOICE function for the selection FOR. If you
    invoke a SELECT form it is this information which is used.
    
    After any form has been invoked, any post-function [/RSE_RECOG=...;func]
    is invoked or the key or specified field is copied to the field which
    invoked the recognition processing.
    
    That's how it works... now we just have to find the problem!
    
    Perhaps you could post some details of the "Recog" form and try turning
    on TRACE so we can see what is happening when you get the error?
    
    Paul.
3082.2Looks like a missing upper-caseIOSG::CHINNICKgone walkaboutTue Aug 03 1993 13:5724
    
    Well...
    
    I'm a little surprised at the way that the recognition works... I expected
    it to use the /RECOG field processing code.
    
    Instead, it actually generates a phandom DSAB (*PH_...) which it then
    uses with an OA$SCL_INIT on your behalf for the RECOG form. From there
    on, it's just like an Index form which should be fine as you have
    things set up. I thought that it would use some special processing to
    map the SELECT context onto the RECOG form, but it doesn't.
    
    The problem seems to be that the form name is appearing in lower case.
    It derives the name of the data-set from OA$SEL_DSAB symbol.
    
    I think you just need to uppercase your DSAB name and it will probably
    start working!
    
    If so, then this is just a bug with the form (DSAB) name not being
    upper-cased.
    
    Let me know what you find,
    
    Paul.
