Single Program

An Interface File for a single program consists of a number of Specification Fields contained between INTERFACE and ENDINTERFACE statements. There are four possible types of Specification Field under ADAM¹, the Parameter Specification, the Help Library Specification, the Message Specification and the Action Specification. They are all optional (depending upon the application).

Specification Fields may consist of a number of subfields as shown in the example below. Examples in this document will use `.' to represent possible lines not shown.

INTERFACE programname
   HELPLIB     HELP_TOP_LEVEL_SPEC
        .
   PARAMETER   parametername_1
      parfieldname   fieldvalue(s)
            .
   ENDPARAMETER
   PARAMETER   parametername_2
            .
   ENDPARAMETER
         .
   ACTION      actionname
      actfieldname   fieldvalue(s)
            .
   ENDACTION
         .
   MESSAGE     messagename
      TEXT     'string'
   ENDMESSAGE
      .
ENDINTERFACE

programname is a character string giving the name of the Interface Module. It must be the same as the name of the program and unique in any given ADAM system.
