[SOLVED] Left pad string with '0' s in DM

I need a way to left pad a string that user entered with 0's in the start to make it a fixed length string.
EG 1234 will become 0000001234


I would like to do it using -SET DM command if possible. In Define File I could use LENGTH and then SUBSTR
SUBSTR('0000000000' ,1,
(10 - LENGTH(&INPUTSTRING));
when i use it in DM it does not like it.

Use the FTOA function (look up the syntax).

A spec of '(F12L)' will move the value into a string of length 12, formatted as you require.

But you must edit the input to ensure it's a valid integer.

GOt it to work. As I am relatively new to WEBFocus Sorry for asking this question.
-SET &LENGTHSTR = 10 - ARGLEN(25,&Input,'I3');
-SET &TESTVAL =  SUBSTR(10,'0000000000' ,1, &LENGTHSTR ,&LENGTHSTR,  'A10V');
-SET &finalinput = IF &Input EQ '' THEN FOC_NONE ELSE &TESTVAL.EVAL|&Input.EVAL;
