Drop first character when it is an underscore

[MChan]

I have a role column similar to below:

Manager

_Tester_Team

_Research_Team

Supervisor

_Helper_Team

How do I drop only the the first character if it begins with an underscore "_" ?

Final output:

Manager

Tester_Team

Research_Team

Supervisor

Helper_Team

if char(string,1) = "_" then string = substr(string,2);

if variablename  =: '_' then variablename = substr(variablename,2);

[data_null__]

Did those underscores come from import from EXCEL.  If so I would fix in EXCEL.
