@@ proc [par1] ... [par8]
	execute a MIDAS procedure
\us\pu
Purpose: 
           Execute a MIDAS procedure from different Midas system dirs.
\up\sy
Syntax:
           @@ proc [par1] ... [par8]
\ys\pa
           proc = name of MIDAS command procedure, type defaulted to '.prg'
                or `proc,entry', if command "ENTRY entry" is used in proc.prg
\ap\pa
           par1 ... par8 = up to 8 actual parameters,
                each parameter may be up to 150 chars. long, but total size
                of all parameters together is limited to 256 char.
\ap\no
Note:    
           If no complete search path for the name of the procedure is given,
	   i.e. just the filename `proc' is entered,
           `@@ proc' searches for the procedure file `proc.prg'
           first in the current directory, and then in all the other
	   directories (max. 4) as given in the Midas-procedure path.
           This procedure path is set via the Midas command
           SET/MIDAS path=...
           The default being the directory specified via the variable MID_WORK.
           Thus by default Midas looks first for a procedure in the current
           directory and then in the one pointed to by MID_WORK, which is
	   by default $HOME/midwork. 
	   Use the command SET/MIDAS path= to change the procedure path.
 
            @ proc  searches in MID_PROC, which is the directory for the
           MIDAS system procedures.
            @a proc  searches in APP_PROC, which is the directory for the
           MIDAS application procedures.
            @s proc  searches in STD_PROC, which is the directory for the
           MIDAS standard reduction procedures.
            @c proc  searches in CON_PROC, which is the directory for the
           contributed procedures.
            @d proc  searches in MID_PROC/pipeline, which is the directory for
           MIDAS procedures used in the ESO Dataflow System for the VLT.
            @p proc  searches in PIPE_PROC, which is the directory for the
           procedures needed for recipes of the pipelines of different
	   VLT-instruments, usually set to $PIPE_HOME/<instrument>/proc
