Re: Use of uninitialized value in substitution iterator in variable expansion

Use of uninitialized value is a warning. To disable it within a given scope use:

no warnings 'uninitialised';

If you're doing templating stuff, you may want to look into one of the many many (many!) templating modules on CPAN (eg. Text::Template). Chances are, there's one that does something you need, so it may be unneccsary to roll your own.

I'm painfully aware of all the available templating systems on CPAN. However, You're looking at the complete extent of my use, and I didn't think I'd need to use an entire Template system in order to expand a few vars. While i could turn off warnings, I thought it best to first see if there was a "proper" way to resolve the warning from being printed. Should I assume that the only way around this type of warning is to disable it in some fashion? That may be entirely possible, but that's all i wanted to find out. thanks for the tip on disableing just that type of warning	[reply]
