If you mean the first letter of variable's indentificator, than it is impossible.
If it was about the wat that variable contains than this way:
Code:
sub Test()
var TextLine='Big line'
var Digit=182341
UO.Print(TextLine[0])
UO.Print(Left(str(Digit),1))
end sub

mhh

var b = 2500

var c = left(str(b),1)

uo.print(c) # return 2 ok..

var d = c * 1000 # bad operation for this type of variable - D


:(
help :?:

:D

var c = val ( left(str(b),1) )



I do not resolve a problem....
I must approximate numbers with ", " for defect

ex...
2,1 or 2,5 or 2,9 return 3

3,1 or 3,2 or 3,3 or 3,4 ecc.... 3,9 .... return 4

3,0 return 3
1,0 return 1

ecc ecc


is possible?

Function Left() (or Right()) work with a string. You can't send value in this function. This function will return a string.

You can't use operations multiple and divide (* and /) with a string. You need in convert the string to value.

Code:
VAR b = 3,2, c, d, e
c = str( b )
UO.Print( c )
d = left( c, 1 )
UO.Print( d )
e = c[0]
UO.Print( e )


Try it. UO.Print() need in string parameter. If you send to this function a value - you can't get legal result.

Try this way:
Code:
sub RoundUp(Value)
return int(Value+0.9999)
end sub


It works this way:
int returns value without ','. That means that 3.0 = 3 and 3.9 = 3. Thats not exactly what we need.
But what do we get after adding 0.9999 (count of '9' is equal to precision you need).
3.0 -> 3.9999 -> 3
3.1 -> 4.0999 -> 4
3.9 -> 4.8999 -> 4
Isn't that what we need?
