Descriptions of the Library Routines 2valueThe argument’s value. Must be of type INTEGER(2), INTEGER(4), REAL(4), REAL(8),LOGICAL(2), LOGICAL(4), CHARACTER*(*), or a single dimension array of one of thesetypes. Can also be of type VARIANT, which is defined in the IFWINTY module.intent_argIndicates the intended use of the argument by the called method. Must be one of the followingconstants defined in the IFAUTO module:• AUTO_ARG_IN: The argument’s value is read by the called method, but not written. This isthe default value if intent_arg is not specified.• AUTO_ARG_OUT: The argument’s value is written by the called method, but not read.• AUTO_ARG_INOUT: The argument’s value is read and written by the called method.When the value of intent_arg is AUTO_ARG_OUT or AUTO_ARG_INOUT, the variable used inthe value parameter should be declared using the VOLATILE attribute. This is because the valueof the variable will be changed by the subsequent call to AUTOInvoke. The compiler’s globaloptimizations need to know that the value can change unexpectedly.typeThe variant type of the argument.
