because there exists about 50 different path locations and each of these paths are extremely long (many subdirectories) and so shortening them down to a single word/symlink (sl01) helps me in identifying the complete path easily - i.e. "sl01" is strategically named.
What I have is as follows:
In my home directory (/user/dept/homes/) I have a program called myprogram.
I want to run myprogram for ~50 different situations as follows:
Situation 1:
Input file located at /vol/bb/cc/dd/ee/ff/gg.
Want to be able create output file (in already existing directory) at /vol/bb/cc/dd/ee/ff/gg/hh.
Situation 2:
Input file located at /vol/ac/ad/ae.
Want to create output file (in already existing directory) /vol/ac/ad/ae/af
Question 1) Initially I was wondering if I could run myprogram from my home directory for all the situations, instead of having copies of myprogram in all the 50 different paths. Is this possible?
Question 2) If not, its fine. But what I do not want to do is have a lot of symlinks in my home directory, instead I was hoping to use a shell script in order to run myprogram from my home directory. Is this possible - i.e. can I use a shell script to execute a program instead of using symlinks.

Absolutely.
If /user/dept/homes/ appears in $PATH, then you can just type myprogram, regardless of the current working directory, and it'll be found (unless there's another executable by the same name in a directory in $PATH which is listed before /user/dept/homes/).
If /user/dept/homes/ is not part of your environment's command search path, you must provide an absolute path: /user/dept/homes/myprogram (or an equivalent tilde expression). Even if /user/dept/homes/ is in your $PATH, providing an absolute pathname is safer, though less flexible.

...how/where in myprogram.c can I sort of "link" the input file to the input location and output file to the output location - hope that makes sense - for e.g. if I have an output file by the name output.dat, how can I say that it goes into the directory /vol/bb/cc/dd/ee/ff/gg/hh
