IR: Arbitrary reference number assigned to the resulting variable (2 to NV [NUMVAR]). If this number is the same as for a previously defined variable, the previously defined variable will be overwritten with this result.
IA: Reference number of the variable to be operated on.
--, --: Unused fields.
Name: Thirty-two character name identifying the variable on printouts and displays. Embedded blanks are compressed for output.
--, --: Unused fields.
FACTA: Scaling factor applied to variable IA (defaults to 1.0).
FACTB: Scaling factor (positive or negative) applied to the operation (defaults to 1.0).

Notes

Forms the natural log of a variable according to the operation:

IR = FACTB*LN(FACTA x IA)
