GRID
RESTRICTIONS ____________
!+GRID+ codes cannot be preceded or followed by normal
characters (use tab codes).
No more than 106 characters are allowed in a !+GRID+ code, nor
may a !+GRID+ code draw a grid wider than 106 characters.
HINTS _____
Use iteration characters in !+GRID+ codes wherever possible.
For example, the following two codes are equivalent, but the
second form is preferred:
!+grid(a,-3,f 6,d,-4,c)+
!+grid(a4,f6,d5,c)+
Both produce:

If an "INVALID PARM" message appears for a !+GRID+ code which
appears to be correct, start INSERTing 1's where they are
implied in the code as iteration or replication factors, until
the error message goes away. This problem generally occurs
only with long, complex codes. As an example of "implied 1's",
the following two codes are equivalent:
!+grid(a3,b,c)+
!+grid1(1a3,1b1,1c1)1+
Both produce:

EXAMPLES ________
A 32-character horizontal line could be created with either of
the two codes: "!+grid(32-)+" or "!+grid(-32)."
A vertical line of 32 characters could be created with the
code: "!+grid()32+."
More examples are given below under "'PIECES' OF GRIDS", and
"BOXES AND GRIDS."
