Description

Determines whether a string conforms to Object Pascal identifier rules.

Call IsValidIdent to determine whether the passed Ident is valid for use as an identifier, such as the name of a component.

An identifier is a sequence of letters, digits, or underscores. Only the first 63 characters are used uniquely. Letters are limited to A-Z and a-z, although the case is ignored. The first character cannot be a digit.
