What is that command that would allow me to know the contents of a string by a given position? For example, if I have this string (quotation marks are not included): " Hi Paul!" and submit number 2, it would return letter H, if I submit 3, it would return letter i, and if I submit 1 or 4, it would return a space.

SubStr(String, StartingPos [, Length])

Thank YOU!!!
But it doesn't seem to return spaces in the beginning of the string:

Code:

line:= " milka"
msgbox, NNN%line%NNN
denj:= SubStr(String, 1 , 1 ) 
msgbox, NNN%denj%NNN

What should I do?

By default, any spaces or tabs at the beginning and end of Value are omitted from Var. To prevent this, use AutoTrim Off beforehand. However, `t (the tab character) is unconditionally omitted. To prevent this, use %A_Tab% in place of `t.

You used "String" instead of "line" as the variable name:

Code:

line:= " milka" 
msgbox, NNN%line%NNN 
denj:= SubStr(String, 1 , 1 ) 
msgbox, NNN%denj%NNN

Should be:

Code:

line:= " milka" 
msgbox, NNN%line%NNN 
denj:= SubStr(line, 1 , 1 ) 
msgbox, NNN%denj%NNN

See SubStr for details.

Hello Z_Gecko!

But now it seems to work fine even without using AutoTrim Off . Why is it so?

AutoTrim docs wrote:

AutoTrim does not affect expression assignments such as Var := " string ". In other words, leading and trailing spaces and tabs are always retained in such cases.
