Since you refer to a second parameter in your script, it needs 2 parameters to successfully run, but this isn't checked for anywhere. If you wrap it as below, then it will fail gracefully if the wrong number of parameters are given (none, one, or 3+).
If you want a different case for 1 parameter, then you can add another statement like if [ $# = 1] for 1 parameter, etc. or put it in a case of $# ($# is the number of parameters, if that isn't obvious from the example.)

Hey..
I've gotten inspired by another thread and used this:
#!/usr/bin/bash
args 2,5 $(<file.list)
It works but I'll like the results separated into different files or back into the 'used'/original files, whatever is easiest.

X2SYS_MERGE(1gmt) Generic Mapping Tools X2SYS_MERGE(1gmt)NAME
x2sys_merge - Merge an updated COEs tables
SYNOPSIS
x2sys_merge -Amain_COElist.d -Mnew_COElist.d
DESCRIPTION
x2sys_merge will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second
file should only contain updated COEs relatively to the first one. That is, it MUST NOT contain any new two tracks intersections (This
point is NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had
to recompute only the COEs between the edited files and the rest of the database.
-A Specify the file main_COElist.d with the main crossover error data base.
-M Specify the file new_COElist.d with the newly computed crossover error data base.
OPTIONS
No space between the option flag and the associated arguments.
EXAMPLES
To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try
x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt
