TO

Syntax​

FOR iterator intial_value TO ending_value ... NEXT [ iterator ] SELECT case_comparison_value CASE lower_bound TO upper_bound ... END SELECT

Description​

The TO keyword is used to define a certain numerical range. This keyword is valid only if used with FOR ... NEXT and SELECT / CASE . In the first syntax, the TO keyword defines the initial value of the iterator in a FOR statement, and the ending value. In the second syntax, the TO keyword defines lower and upper bounds for CASE comparisons.

Example​

'' this program uses bound variables along with the TO keyword to create an array, store random

FOR it = minimum_temp_count TO maximum_temp_count

   '' display a message based on temperature using our min/max danger zone bounds

   SELECT array( it )

          CASE min_low_danger TO max_low_danger

             COLOR 11

             PRINT "Temperature" ; it ; " is in the low danger zone at" ; array( it ) ; " degrees!"

          CASE min_medium_danger TO max_medium_danger

             COLOR 14

             PRINT "Temperature" ; it ; " is in the medium danger zone at" ; array( it ) ; " degrees!"

          CASE min_high_danger TO max_high_danger

             COLOR 12

             PRINT "Temperature" ; it ; " is in the high danger zone at" ; array( it ) ; " degrees!"

          CASE ELSE

             COLOR 3

             PRINT "Temperature" ; it ; " is safe at" ; array( it ) ; " degrees."

   END SELECT

NEXT it

SLEEP
