I presume you've made a few typos in your example:

cNumber = transform( alltrim(str(nNumber)), "@R " + cMask)

(i.e. you probably wanted to have: 1. a comma rather than a "+" between the expression and the format code; 2. a space between the "@R" and character mask)

IIRC in the case when the first parameter to TRANSFORM() is a string value, "A" in a mask would be the equivalent to "X" -- thus variable cNumber would contain the value "6 7849" rather than "A 6789"
