Greater than or Equal to (GE) on a character variable

[DeepSiv]

al toHi all

I would like to understand how SAS processes when we give GE or LE on a alphanumeric field. It doesn't give an error, but I would like to know how it handles it.

Eg: IF TEST GE "5000" where test is a character field. What values come true for this condition?

Scroll down to the section entitled "Character Comparisons".

What may not be immediately obvious is that, at least with ASCII character sets,

'ABC' GE '5000'

is true
