awk array - first and last occurance
What I'm trying to do is, using awk, loading the log file into an array matching column 2, counting the match and finding the first occurance and last occurance of column 1 being it a date.
08052006:AAA
08052006:AAA
08052006:BBB
09052006:AAA
15052006:BBB
11052006:CCC
19052006:CCC
15052006:BBB
20052006:CCC
This is the output I'm trying to achieve:
ID :Count:First Occurance:Last Occurance
AAA:3 :08052006 :09052006
BBB:3 :08052006 :15052006
CCC:3 :11052006 :20052006
I've managed to produce the first two columns of output (I guess that's the easy part), but I just can't work out how to print the first date occurance and the last
Can anyone give me some pointers, please?

xcmscccofcolormap
XcmsCCCOfColormap(3) XLIB FUNCTIONS XcmsCCCOfColormap(3)
NAME
XcmsCCCOfColormap, XcmsSetCCCOfColormap - query and modify CCC of a colormap
SYNTAX
XcmsCCC XcmsCCCOfColormap(Display *display, Colormap colormap);
XcmsCCC XcmsSetCCCOfColormap(Display *display, Colormap colormap, XcmsCCC ccc);
ARGUMENTS
display Specifies the connection to the X server.
ccc Specifies the CCC.
colormap Specifies the colormap.
DESCRIPTION
The XcmsCCCOfColormap function returns the CCC associated with the specified colormap. Once obtained, the CCC attributes can be queried or
modified. Unless the CCC associated with the specified colormap is changed with XcmsSetCCCOfColormap, this CCC is used when the specified
colormap is used as an argument to color functions.
The XcmsSetCCCOfColormap function changes the CCC associated with the specified colormap. It returns the CCC previously associated with
the colormap. If they are not used again in the application, CCCs should be freed by calling XcmsFreeCCC. Several colormaps may share the
same CCC without restriction; this includes the CCCs generated by Xlib with each colormap. Xlib, however, creates a new CCC with each new
colormap.
