    MODULE
	Tackon.c

    DESCRIPTION
	Get three strings on Commandline
	a path, a name and a suffix,
	build a filename from these three
	strings and write it to StdOut

    NOTES
	Kickstart 2.0+ required
	compiles w/ Dice 2.07R - inline-pragmas required
	compiles w/ SAS/C v6.51

    BUGS
	there is a strange behaviour if compiled w/ DICE;
	- I cannot say why, but If You do not specify
	each input-slot, You will get a Enforcer-Hits;
	for that reason, I'll distribute Chris' SAS-executable


    TODO

    EXAMPLES
	> tackon xx yy zz
	xx/yy.zz

	> tackon xx :yy -zz
	:yy-zz

    SEE ALSO
	Suffix, PathPart, FilePart
