I would use a dictionary to store the axis names and have the lookup
match the axis numbers assuming your speaking in Python...
axis_name = {0:'X', 1:'Y', 2:'Z', etc.}
The using eval() to pull out the axis names like this in a for loop.
for i in axes:
print eval('axis.' + axis_name[i] + '.jog-enable')

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
