B.1.1 Usage

The usage of calc is

   stilts <stilts-flags> calc table=<table>
                              [expression=]<expr>

Parameter values are assigned on the command line as explained in Section 2.3. They are as follows:

expression = <expr>

An expression to evaluate. The functions in Section 9.5 can be used.

table = <table>

A table which provides the context within which expression is evaluated. This parameter is optional, and will usually not be required; its only purpose is to allow use of constant expressions (table parameters) associated with the table. These can be referenced using identifiers of the form param$*, ucd$* or utype$* - see Section 9.2 for more detail.
