Kumar,
From pages 186/187 of IBIS 5.0
| The syntax for this string is:
|
| 1. Neither names nor individual values can contain white space characters.
| 2. Parameter name/value pairs are always enclosed in parentheses, with the
| value separated from the name by white space.
| 3. A parameter value in a name/value pair can be either a single value or a
| list of values separated by whitespace.
| 4. Parameter name/value pairs can be grouped together into parameter groups
| by starting with an open parenthesis followed by the group name followed
| by the concatenation of one or more name/value pairs followed by a close
| parenthesis.
| 5. Parameter name/values pairs and parameter groups can be freely
| intermixed inside a parameter group.
| 6. The top level parameter string must be a parameter group.
| 7. White space is ignored, except as a delimiter between the parameter name
| and value.
| 8. Parameter values can be expressed either as a string literal, decimal
| number or in the standard ANCI 'C' notation for floating point numbers
| (e.g., 2.0e-9). String literal values are delimited using a double
| quote (") and no double quotes are allowed inside the string literals.
| 9. A parameter can be assigned an array of values by enclosing the
| parameter name and the array of values inside a single set of
| parentheses, with the parameter name and the individual values all
| separated by white space.
Note 2. above:
| 2. Parameter name/value pairs are always enclosed in parentheses, with the
| value separated from the name by white space.
The following (from Ambrish and Ken) follow this rule:
(abc 10.1 20.2 30.3 )
The following example that you propose for multi-row tables violates this rule:
(name (a11 a12 a13) (b11 b12 b13))

a single row table can be passed as
(name a11 a12 a13)
multi rows
(name (a11 a12 a13) (b11 b12 b13))
