Do this:

lcMask = "A XXXXXXX" && this is Cyrillic A, you can use whatever letter you want.
lnNumber =67849
lcNumber = CHRTRAN(transform( ALLTRIM(STR(m.lnNumber) , "@R "+ m.lcMask),[A],[A])

Other approach:

lcMask = "XXXXXXX"
lnNumber =67849
lcNumber = transform(ALLTRIM(STR(m.lnNumber) , m.lcMask)
lcNumber = [A ]+lcNumber
