Code (glbasic) Select



IF LEN(self.button_Name$ )<7

     INPUT self.button_Name$  , self.x, self.y+50

ENDIF

Basically I want do , using input command, I only can write N( 7 ) characters.

DEBUG (or use PRINT) LEFT$(self.button_Name$,7)

Why not use INKEY$?. So, you could filter the characters entered in real time.

Code (glbasic) Select

GLOBAL name$, N=7, letter$

WHILE LEN(name$)<=N
	letter$=INKEY$()
	name$=name$+letter$
	PRINT name$+"_",0,0
	SHOWSCREEN
WEND

INKEY would indeed be the more professional way of doing it.

Thanks MSX I don't thought-out, really this is I need.

The problem in input you can't say the max number of chars...

Thanks a lot. :booze:
