The table gives the types of capabilities that can be determined via calls to Query Capabilities Integer or Query Capabilities Real. The first column lists the capability. The second column gives the integer code to be used in the call. Alternatively by including the FORTRAN file ’IDI_PAR’ in a program the codes can be accessed using the mnemonics given in the third column. The final column describes the type and size of the return arguments. An entry of n signifies a single integer value and an entry of n() implies an array of integer values. Values r and r() signify single and multiple real values, and l and l() imply single and multiple logical values. The logical values are represented by integers with zero meaning ’false’ and any other value meaning ’true’. The global constant IDI__MAXCP can be used to dimension the arrays passed to the query routines; this is defined in the file ’IDI_PAR’.
