BASIC CODE: VALIDATION
Examples of validation logic.
Code Example
* Checking to see if they input a number
if num(ANS) then
   gosub good.value
end else
   error.flag = 1
end
*
*
* In this program snippet, we are check for a limited set of answers, each
* with it's own logical path
begin case
   case MYINFO = "A" ; gosub do.addition
   case MYINFO = "S" ; gosub do.subtraction
   case MYINFO = "K" ; gosub do.known.formula
end case
*
* This time we want to iterate through a list
* and validate each element separately.
loop
   CURRENT = FULL.LIST<1>
   FULL.LIST = delete(FULL.LIST,1)
until FULL.LIST = '' do
   if oconv(CURRENT,'MCA') = CURRENT then
      * This is alphabetic, okay!
      GOOD.LIST<-1> = CURRENT
   end
repeat
