Translate field in FCE

Generally FCE cannot be translated, like normal tables. How we may use two fields like field_fr, field_en, and then display the related info according to the language.

  
EX:
      
10 = COA
10 {
#Translation for primary language (L=0) 30 = TEXT 30.field = field_slide_info 30.stdWrap.wrap = <p>|</p> 30.if { value = 0 equals.data = gp:L }
    #Translation for second language (L=1)
40 = TEXT 40.field = field_slide_info_en 40.stdWrap.wrap = <p>|</p> 40.if { value = 1 equals.data = gp:L } }
