Limits, A Few Minor Ones
The following limits apply.
- There must not be any ASCII TAB characters in the data. This
is the primary limit as the ASCII TAB character is the
delimiter in rdbtables.
- There must not be any pipe characters `|` used or entered as
data when using the operator 'etbl'.
- All of the Compare operators and Logical constructors are
reserved and should not be used as column names (they are all
lower case and four characters or less). They are: 'gt', 'ge',
'lt', 'le', 'eq', 'ne', 'or', 'and', 'null', 'mat', and 'nmat'.
