Introduction

Each program parameter must have a Parameter Specification in the Interface File. The Parameter Specification is of the form:

PARAMETER parametername
   parfieldname fieldvalue(s)
         .
ENDPARAMETER

where parametername is a character string giving the program parameter name which is used in the program (in a call to DAT_ASSOC or PAR_GETnx etc.). Case is not significant in parameter names. For a discussion of valid parameter names, see Appendix .

The possible subfields in the Parameter Specification are described in detail below - they are all optional and, apart from TYPE, which must appear before DEFAULT, RANGE or IN fields, the order is unimportant.
