Performing FAST-TCF Curve Operations

PERFORMING FAST-TCF CURVE OPERATIONS

Description keyword following words
Curve operation oper oper command + necessary words (depending on operation)

Many curve processing operations and functions are available. The syntax is common for all types of curve operation:

  1. The first word is oper and is followed by:
  2. The operation/function name e.g. ADD, INT.
  3. The required number of arguments for the operation, e.g. ADD requires two arguments, a curve and either a curve or a value.
  4. The remainder of the line may contain optional requests.
  5. Any optional requests can occur after the arguments.
  6. Curve numbers must be in the format: #<curve number>
  7. An output curve is always needed - for operation commands such as hic, hicd, tti, 3ms, err, the curve will be copied and the operation is executed on the copied curve.
  8. A curve tag containing a wildcard or a curve group can be specified as the first curve input for any curve operation. If a curve tag contains a wildcard or if a curve group is specified then the curve operation will be repeated for each curve that either the tag matches or is in the curve group.
e.g. oper hic node_acc 1.0 15E-3 label Hic-ed node accn
(hic) (curve tag) (scale=1.0) (15ms period) (label)

In T/HIS 9.2 onwards, the user can operate on multiple input curves (only the first curve can be multiple at the moment) using the wildcard "*". For example, to multiply all curves starting with the tag acc :

e.g. oper mul acc* 9810.0
(multiply) (on all curves with tag acc*)
