Hi all,
Is there a length limit to the editable string (suggestion$) in the
function READ_STRING$?
answer$=read_string$(" edit ",suggestion$,request$,length,xpos,ypos)
If there is any info about it, where can I find it?
Thank you in advance.

if you need more use this
careful with menu_rext pre 8.04
the string length (name$(nr)="1234567890")
must not exceed the the given length
(dim name$(nr,length)
otherwise your system will crash
100 CLEAR
110 nr = 0 : DIM name$(nr,60), name%(nr)
120 :
125 name$(nr) ="12345678901234567890123456789012345678901234567890"
130 name%(nr) = 16384
140 :
170 :
180 REPeat loop
190 REMark this works with menu_rext 7.66
200 :
210 REMark r = LIST_SELECT ("Test",name$,name%,,,,,)
220 :
230 REMark workaround for 8.0x but not 7.66
235 :
240 REMark r = LIST_SELECT (" Test ",name$,name%,,,,,)
245 :
250 SELect ON r
270 = -2
290 s = name%(0)&&(BIN$ (16,16))
300 IF s = 256
310 PRINT #1, name$(0)
320 END IF
350 = -1 :EXIT loop
370 = REMAINDER
380 END SELect
390 END REPeat loop

Thanks for your reply.
I'm using v8.4
The listing above listing proves that we can't trust 'read_string$'.
I have noticed that there are in fact 2 limits:
1 ) answer$=read_string$(" edit ",suggestion$,request$,length,xpos,ypos)
: suggestion$ seems to be safe up to 100 characters.
(system locks at 150). So, the limit is somewhere between 100 and 150.
2) read_string$(.....) returns out of range if the window is too small
to display the string.
Conclusion , at least for me, avoid read_string$.
Thanks for your help.
Have a fine day.
