Show graphs previously saved
----------------------------

    ^showgph^ [filespec] [ ^, d^ir^(^directory^) a^sis ^l^ist ]

Description
-----------

^showgph^ shows graphs previously saved as .gph files and present in
the same directory or folder. Graphs are drawn one at a time in
alphanumeric filename order.

filespec can take one of the following forms:

             (nothing) -- treated as ^*.gph^
 ^*^                                   ^*.gph^
 ^*.gph^                               ^*.gph^
 name                                name^.gph^
 name.^gph^                            name^.gph^
 name^*^                               name^*.gph^
 name^*.gph^                           name^*.gph^

In addition, ^?^ means any single character. For example, 
^t?^ will pick up any of ^t0^ to ^t9^ or ^ta^ to ^tz^ if they exist. 


Options
-------

^dir(^directory^)^ specifies a directory or folder in which to look.
    The default is the current directory as indicated by ^cd^.

^asis^ specifies that graphs should be shown as is. By default, each
    graph is shown with its filename shown as a ^t1title^. ^asis^ turns
    off this feature.

^list^ specifies that graph filenames should be listed in alphanumeric 
   order. Note that by default (and necessarily) the results of a ^dir^ 
   command are shown on the monitor, although not necessarily in 
   alphanumeric order. 


Remarks 
-------

Except under Unix, any log file open when ^showgph^ is invoked is closed 
temporarily, and the results of a call to ^dir^ are logged to a temporary 
file. Thus such results will not be shown in the log file. The ^list^ option 
should be used if it is desired to have a list of graph filenames in the 
current log file. 

Under Unix, the system ^ls^ is used to write to a temporary file and any 
log file open is not affected. 


Examples
--------

    . ^showgph k*^
    . ^showgph k*, d(\another\folder)^
    . ^showgph k*, d(\another\folder) l^
    . ^showgph k?^
