I'm trying to identify if the first character of a variable is a number or string.

My variable is %myvar and I am running a loop which is picking up cusips (numbers) and tickers (strings) from a group.

I am using @left to identify what the first character.

However, I need something to tell me if it is a number or a letter.

Does EViews have such a command?

Thanks!

Code: Select all


@isna(@val(@left(%myvar,1)))

Will return 1 if it is a character, and 0 if it is a number.
