.hl 2 CDATE - Compress date

The CDATE routine will convert a  DEC format ascii date (DD-MMM-YY) into 
a 7 character date string (DDMMMYY) by removing the hyphens. The 7 character 
Ascii date is often encountered in FMS data handling.

The input string can be any string type - only the first 9 characters are used.
They are moved, with the hyphens stripped out, to the first 7 characters
of the output string, which can also be of any type.
}

{*TECH*

This routine makes no validity checks of the incoming string and will ,in 
fact, remove the 3rd and 7th characters of any CH9 string returning a CH7
string. It will work with any type zero or type one strings as long as the 
effective string lengths are 9 chars for input and 7 chars for output.
