Note:  
          This command is especially useful inside MIDAS procedures.
          No output is generated, only the integer keyword MID$INFO is filled
          as follows:
\\
          If the keyword could not be found, MID$INFO(1) = 0.
\\
          Otherwise MID$INFO(1) contains the type of the keyword,
\\
          1 = integer, 2 = real, 3 = character, 4 = double precision.
\\
          MID$INFO(2) = the no. of elements of the keyword,
          MID$INFO(3) = the no. of bytes per element,
          MID$INFO(4) = the lock no. of the keyword,
          MID$INFO(5) = the time of last iwrite access of the keyword.
\\
          The function M$EXISTK of the command COMPUTE/KEYWORD provides
          similar but less detailed information.

Examples:
\ex
          INFO/KEYW durazno 
            If keyword DURAZNO is a double precision keyword of 6 elements
            and unlocked, then:
\\
            MID$INFO(1) = 4, MID$INFO(2) = 6, MID$INFO(3) = 8, MID$INFO(4) = 0.
