I think you are doing simple substitution so
use the normal Rev syntax... +one less character

Rev == Foxpro
get bobTest&1 == get $ bobtest.1
get jimTest&1 == get $jimtest.2

on mouseDoubleUp
  put "happy" into bobTest
  put "I am glad" into jimTest
  --simple  ---------------
  get bobTest&1
  get jimTest&2
  
  --indirection using 'do' ------------
  put " get $bobtest.1" into foxString
  replace "$" with empty in foxString
  replace "." with "&" in foxString
  do foxString
  put it into part1
  
  put " get $jimtest.2" into foxString
  replace "$" with empty in foxString
  replace "." with "&" in foxString
  do foxString
  put ".   "& it after part1
  answer part1
end mouseDoubleUp
