                                                NOTATION STANDARDS
Definitions:

x,y                           -A point in a 100x100 coordinate system. The X axis is from the
                                left side of your screen to the right side, the Y axis is from the
                                tool bar to the status bar. Thus 50,50 is the center of your
                                screen; 1,1 is the upper left corner; 100,1 is upper right; 1,100
                                is lower left corner; 100,100 is lower right. Used in commands
                                that instantiate objects to specify the location of the upper left
                                corner of the object.

instantiate             -To make an instance of. Commands such as CALENDAR, MENU,
                                LISTPICK, CHOOSE, DIALOG, READ, UPDATE, APPEND, LOOK, etc.,
                                instantiate objects.
c or coll or
collection               -A collection name.

tname                     -A tablename.

fname                     -A fieldname.

fdesc                      -Composed of: fieldname [(format)] See format overrides.

filename                 -The name of a file. Full-path names are supported everywhere.

%v                          -A variable name. See variables.

template                 -Refers to a date template. See template.


Conventions used in command syntax skeletons:

                Items shown in upper case are required unless specifically excepted in
                the text of the command description.

                Items shown in lower case are something that you must specify.

                Items enclosed in [brackets] are optional.


Multi-line commands:

                The basic syntax rule for any command or statement is as follows:
                One statement per line and no period at the end of any statement.

                By one statement per line we mean do not put two commands on the
                same line. However, you may take more than one line for a single
                command. To do that, use the hyphen as a continuation indicator.
                For example,

                                Find -

a -                                                                                           

where -                                                  
                city=metropolis

 

is the same as:  Find a where city=metropolis

                W ithout the hyphens we will not interpret this multi-line command
                correctly. The hyphen allows continuation within a word, so to continue               
                between words requires either a space before the hyphen or indent the  
                next line.
