is used to query the value of optional parameters available to supported problem solving functions in Chapter H
is used to query the current values of options. It is necessary to initialize optional parameter arrays using h02zkc
before any options are queried.
will normally return either an integer, real or character value dependent upon the type associated with the optional parameter being queried. Some real and integer options also return additional information in cvalue
. Whether the option queried is of integer, real or character type, and whether additional information is returned in cvalue
, is indicated by the returned value of optype
Information on optional parameter names and whether these options are real, integer or character can be found in Section 11
See the example programs associated with the problem solving function you wish to use for a demonstration of how to use h02zlc to query options.
