Issues with Expect
Here is a snippet of code that work for me:

Code:
expect  "abc" {send_log "abc found" } \
            "def"  {send_log "def found" } \
            "123" {send_log "123 found}

however the following does not and according to the book "Exploring Expect" it should be equivalent:

Code:
expect  { "abc" {send_log "abc found" } 
               "def"  {send_log "def found" } 
               "123" {send_log "123 found}
             }

I'm using expect version 5.43.0 and the date on the book is 1996.

Another issue I have that I can not understand why is:

in response to "ls -l file",
Code:
"expect "drwx" {send_log "file found"}

the log file ends up with "file found", however,
Code:
"expect "^drwx" {send_log "file found"}

the log file ends up with nada!

Again the book says it should work with the anchor but not for me. To ensure that the d really is the first character in the out put from ls I did "ls -l file | od -C" and the dump shows the d as first with, no leading unprintable characters much less any printable ones!

These may seem like trivial issues but I need to make the processing more complex and understanding what is going on would really help.


Thanks...twk

XmScrollVisible(library call)											     XmScrollVisible(library call)

NAME

       XmScrollVisible -- A ScrolledWindow function that makes an invisible
	descendant of a ScrolledWindow work area visible

SYNOPSIS

       #include <Xm/ScrolledW.h>
       void XmScrollVisible(
       Widget scrollw_widget,
       Widget widget,
       Dimension left_right_margin,
       Dimension top_bottom_margin);

DESCRIPTION

       XmScrollVisible makes an obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible. The function re-
       positions the work area and sets the specified margins between the widget and the nearest viewport boundary. The widget's location relative
       to  the	viewport determines whether one or both of the margins must be adjusted. This function requires that the XmNscrollingPolicy of the
       ScrolledWindow widget be set to XmAUTOMATIC.

       scrollw_widget
		 Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured descendant.

       widget	 Specifies the ID of the widget to be made visible.

       left_right_margin
		 Specifies the margin to establish between the left or right edge of the widget and the associated edge  of  the  viewport.   This
		 margin is established only if the widget must be moved horizontally to make it visible.

       top_bottom_margin
		 Specifies  the  margin  to  establish between the top or bottom edge of the widget and the associated edge of the viewport.  This
		 margin is established only if the widget must be moved vertically to make it visible.

       For a complete definition of ScrolledWindow and its associated resources, see XmScrolledWindow(3)
