PRINT/KEYWORD [key_list] [since]
	print contents of keywords
\us\pu
Purpose: 
          Print contents of keywords.
\up\sy
Syntax:
          PRINT/KEYWORD [key_list] [since]
\ys\pa
          key_list = one or more keywords separated by a comma (no spaces!)
\\
             or '*' (wildcard option) where all keywords are printed
\\
             or a `keyword catalog' indicated via extension ".cat";
\\

             defaulted to '*'
\ap\pa
          since = lower update time limit;
\\
             only those keywords of `key_list' which have been updated since
             that time are printed
\ap\sa

          ASSIGN/PRINT, READ/KEYWORD, SHOW/KEYWORD, HELP/KEYWORD
\\
          also chapter 3 of the MIDAS Users Guide, volume A
\as\no
Note:  
          PRINT/KEY produces the same output as READ/KEY on the device
          specified via ASSIGN/PRINT.
\\
          Each keyword gets a timestamp when is is modified. This timestamp is
          a number giving the current time expressed in seconds elapsed since
          1st January, 1970.
\\
          The parameter `since' has to be given as such a number. To obtain
          the current time in that format use the M$SECS function in MIDAS.
\\
          A `keyword catalog' is simply an ASCII file with records containing
          one or more keywords (separated by comma).
\on\exs
Examples:
\ex
          PRINT/KEY in_a 
          Print contents of keyword IN_A.
\xe\ex
          PRINT/KEY  keywo.cat
          Print contents of all keywords in the `keyword catalog' keywo.cat.
\\
          E.g. if the ASCII file keywo.cat contains the two records:
\\
          in_a,in_b
\\
          inputi
\\
          contents of keywords in_a, in_b and inputi would be printed..
