Topic: character or number

[TopoWAR]

hello, as if the string is a number or character (letter)
example:

Code: [Select]

(setq x "b" x1 "1")I need a command that I distinguish between number and letter,
something like dos_strischar of DOSLib but in AutoLISP
thanks

Code: [Select]

(wcmatch <string> "#")

Code: [Select]

(type (read <string>))

Code: [Select]

(< 47 (ascii <string>) 58)

Code: [Select]

(vl-every '(lambda ( c ) (< 47 c 58)) (vl-string->list <string>))
