I receive a number as input

length = ln = 7

if input = 25
I need to add zeros to make make it as - 0000025 (a total length of ln)

if input = 9
I need to add zeros to make make it as - 0000009 (a total length ofln)

write $translate($justify(input,ln)," ",0)

Assuming, your input value is an integer, you have , along with the other solutions, one more:

// this works as long as len  < 145
//
set len =  120
set inp = 12345
write $e(1E120_inp,*-len+1,*)

// of course, if the len is shorter than, say 10,
// then you can use smaller constans like
//
set len=10
set inp=9
write $e(1E10_inp,*-len+1,*)

A good (or even a bad) side effect of the above solution is, if you get an input value which is LONGER than the length, it will be truncated to the given length

Many ways to do it, my way:

USER>Set input=25
 
USER>Set ln=10
 
USER>Set $Piece(Pad,"0",ln-$Length(input))="0"
 
USER>Set Padded=Pad_input
 
USER>Write
 
Pad="00000000"
Padded="0000000025"
input=25
ln=10

Another possible solution to this,

ClassMethod PadNumberWithZeros(number As %String, ln As %Integer) As %String
{
    set num = number
    while $length(num) < ln {
        set num = "0" _ num
    }
    return num
}

Returns 0000025 for 25 and 0000009 for 9 for the provided test cases

The object script expression: $TRANSLATE($JUSTIFY(input,length)," ","0")
