When a sucro is called without a pathname, it will be looked for
in this order from directories
1. current data path
2. sucropath, given by sucropath=<path> in SURVO.APU
(e.g. sucropath=D:\SUCROS\ )
3. <Survo>\U\S\ (<Survo> is the main directory of SURVO MM.)
4. <Survo>\U\TUT\
5. <Survo>\S\
6. <Survo>\TUT\
If the sucro does not exist in these directories, an error message
'Sucro <name> not found!' will be displayed.
By the sucro command
/WHICH <name_of_sucro>
the current instance of a sucro is automatically detected.
