MIDAS procedures

Each MIDAS command must have a procedure, written in the MIDAS Control Language (MCL), which handles the command line parameters and defines the keywords used by the actual application coded. The procedure will execute the basic modules (i.e. using the RUN command). The rules for MIDAS procedures are:

• Command line parameters must be defined by the CROSSREF command which must be the first command.
• Parameters must be defined by a DEFINE/PARAMETER command. These commands must follow immediately after the CROSSREF command.
• Local variables must be declared with the DEFINE/LOCAL command.
• Each module must contain a comment header block which defines name, purpose, author, version etc. (see Section ).
• Indentation of at least two columns must be made for each level of IF-THEN/ELSE/ENDIF and DO/ENDDO statements.
• All MIDAS commands must be specified completely, i.e. 6 characters for the command verb and 4 characters for the qualifier.
