EASE OF FORMS DESIGN
If the printing delimiter is to come first, use
[ ESCAPE [ fieldtag ...ESCAPE ]
If the printing delimiter is to come last, use
ESCAPE [ fieldtag ...ESCAPE ]
In the case where a field begins with ESCAPE [ and ends with ], the terminal will insert
ESCAPE ] if a following field also starts with ESCAPE [. As a result VPLUS will reject the
form layout. This terminal feature can be avoided by properly using the above rules for
mixing delimiters. Refer to Figure 3-6. for examples of different ways to layout a form.

Field Tag
Regardless of the technique used to delimit the fields, each field must be identified by a
"field tag". This tag consists of (USASCII only) letters of the alphabet (uppercase or
lowercase), digits, or the underline (). The first character must be alphabetic. Since the
field tag must be specified within the field delimiters, it is limited to a length less than or
equal to the number of characters in the field. Thus, if you have a one-character field, its
