Printing value fields with negative sign??

Question

Hello Experts,
I have developed a interface, which writes the invoice data to application server/unix, this is a notepad. My specifications are as below,
MWSK1(2)   TaxCode                         65     2     KONV-MWSK1     
KWERT(13)  Condition Value                  67     13   KONV-KWERT     
KSTEU(1)  Condition Control                80     1     KONV-KSTE
I have to print KWERT value from 67th position until 13 positions, meaning until 80 positions, fine. My code is as below,
  MOVE: wa_invoice_price-mwsk1  TO unix_file+64(2).
  WRITE: wa_invoice_price-kwert    TO unix_file+66(13) RIGHT-JUSTIFIED.
  MOVE:  wa_invoice_price-ksteu    TO unix_file+79(1),
So, it printing like below (pls. note 0.04 minus value in right bottom corner)
P26701ZCG620101006C          100.00         0.00USD  1    UGL            0.00A A 9
P60001ZF3520101006C          100.00         0.00USD  1    UGLG          0.04-H B 9
But, business want to have like below (pls. note the DIFFERENCE for 0.04 minus value in right bottom corner),
P26701ZCG620101006C         100.00        0.00USD  1    UGL               0.00   A A 9
P60001ZF3520101006C         100.00         0.00USD  1    UGLG             0.04 - H B 9
meaning, the 13th position should be negative sign (if at all any value does have a negative sign, else its normal)....so, the negative sign should sit on 13th postion. As am using WRITE statement with RIGHT JUSTIFIED am facing thisissue!! as u know we can not send a 'P' type value to unix/apps server, pls. let me know how to get it done?
Thank you

why can't the user live with a leading sign, like '-   0.04'?  If possible, do
shift <fieldname> circular up to '-'.
Or, if value is less than zero, set another variable to '-', else set to space, and multiply value with '-1', like:
if <field> < 0.
   lv_sign = '-'.                " neagtive value
  <field> = <field> * '-1'.  "reverse the sign
else.
lv_sign = space.          "positive value
endif.
then, adjust your field length and insert a sign column or simply add a column for the sign....
