3.10 Control Tokens
• Sum with One Parameter – The tAttrSum Token
This token replaces the tFuncVar(SUM) token, if the SUM function takes one parameter only. This is the only tAttr
token that behaves like a real operator.
Token tAttrSum, BIFF2:
Offset Size Contents
0 1 19 H
1 1 10 H (identifier for the tAttrSum token)
2 1 Not used
Token tAttrSum, BIFF3-BIFF8:
Offset Size Contents
0 1 19 H
1 1 10 H (identifier for the tAttrSum token)
2 2 Not used
Example: The formula =SUM(1) is represented with the token array tInt(1), tAttrSum; instead of the token array
tInt(1), tFuncVarV(SUM).
• Assignment in Macro Sheet – The tAttrAssign Token
In macro sheets it is possible to replace the SET.NAME function with an assignment-style formula. The usual syntax
=SET.NAME(name,value) will be replaced with the command name=value then.
Example: The macro sheet function =SET.NAME(myname,1) is represented by the token array
tNameV(myname), tInt(1), tFuncVarV(SET.NAME).
The used name is contained in a tName token.
The same can be done with the assignment-style formula myname=1. The token array of this function is
tAttrAssign, tAttrStr("myname"), tAttrInt(1), tFuncVarV(SET.NAME).
Now, the used name is given as string in a tStr token, not in a tName token anymore.
Token tAttrAssign, BIFF2:
Offset Size Contents
0 1 19 H
1 1 20 H (identifier for the tAttrAssign token)
2 1 Not used
Token tAttrAssign, BIFF3-BIFF8:
Offset Size Contents
0 1 19 H
1 1 20 H (identifier for the tAttrAssign token)
2 2 Not used
In an assignment-style formulas the tAttrVolatile token will not be the first token in the formula, but it will follow the
tStr token containing the name used in the assignment (as usual, this can also be a tAttrSpaceVolatile token).
Example: The assignment-style formula myname=NOW() is represented by the following token array:
tAttrAssign, tStr("myname"), tAttrVolatile, tFuncV(NOW), tFuncVarV(SET.NAME).
See also the examples for the tAttrSpace token below.
