You could do.

dim selection as string

while selection = ""
selection = INKEY$
wend

IF selection = "1" THEN CALL CONVGBP
IF selection = "2" THEN CALL AUDGBP
IF selection = "3" THEN CALL CADGBP
IF selection = "4" THEN CALL NZDGBP
IF selection = "5" THEN CALL USDGBP
IF selection = "6" THEN CALL EURGBP
IF selection = "7" THEN CALL ENDOFDAY
IF selection >= "8" THEN
ELSEIF selection <= "0" THEN
