CLEARDATA

Synopsis

CLEARDATA

Description

The CLEARDATA statement flushes (clears) all remaining data stored in the input stack by the DATA statement. Following CLEARDATA, the INPUT statement issues a user prompt, rather than automatically receiving data stored by the DATA statement.

Examples

The following example illustrates the use of the CLEARDATA statement:

DATA "New York","Chicago","","Annapolis"
FOR x=1 TO 4
  INPUT cityname
  IF cityname=""
   THEN CLEARDATA
   PROMPT "Missing name: "
   INPUT cityname
  ELSE
   PRINT cityname
NEXT
