how to write FOR-NEXT

10 FOR A=1 TO 10
20 PRINT SHAHZAIBBAIG
30 NEXT A

Where A is a variable , 1 TO 10 this will PRINT SHAHZAIBBAIG 10 times, you can PRINT more than ten time, its is useful and short STATEMENT of GW-BASIC , NEXT Command is must if u donot write at the end the loop will not work and give you syntax error.

Some Examples

10 FOR A = 3 TO 28 STEP 5
20 PRINT A
30 NEXT A

Where STEP 5 will PRINT Like this 3 then 8 then 13 then 18 ....

You Can also do this
