ESC Key

[Nancy Palmquist]

Scott,

Flow is always one of the hardest things to get a handle on.

Think of @wef, @wlf, @wbl, @whp, @wuk  - think that is all.

As processes that run when an event happens.  It runs until it hits 
SCREEN, END, SKIP (couple of other commands but the list is in the 
docs.)  Then the event is over and it moves to the next field.

When you press ESC - you are moving from top to bottom through the INPUT 
table.

Input starts at line 1 and accomplishes lines until you hit END, EXIT, 
etc. (again the list is in the docs.)

Consider INPUT processing for regular input, output, @key, chain stuff.

Call stuff is a little different - a call ends at END or Screen (I often 
forget this last one.)

Auto runs before a record is displayed - Auto is for establishing data, 
setting variables, passing data from one table to the next,  not doing 
input stuff.

Then you have @once, @done, @menu and @entsel - sequence logic that run 
at specified times - obvious from the names, and finish when they hit an 
END.  Records are not locked in these routines so data changing should 
not be done here on the current record.  Be careful.

This is very brief and can take hours to get clear but if you take a 
table apart and think of each section as a separate little program, it 
works.

My tables usually work like this:

INPUT: Put user in data entry
     @wlf processing checks data in fields that you just left.  If the 
field is blank or has the wrong value and they should not continue plop 
them back in the field.  As you move through the field you should look 
at each piece of data and write these.

ESCAPE is pressed.  Now you move forward in INPUT processing and here is 
where I check relationship data.  You know if it is tuesday and the moon 
is full then field 10 should be YES.  That kind of stuff. If I find a 
problem, put then back in the bad field, add a goto the repeats the test 
you just did when they press ESC again.
Save the data as needed.

Give them the next screen when you are happy and repeat that process for 
each screen.

I hope this is not too general, but you may find some tips of use on my 
web page that go into more detail.
