(c) Numeric variables are basically variables named with just a __________ or a word. (letter/value)

(d) The loop will not execute if the start value is more than the __________ value and the STEP is positive.(end/open)

(e).The --------- sign tells QBASIC that this variable contains text. ($/#)

(f). QBASIC can execute a part of a program more than ___________ (once/thrice)

(g) In QBASIC, there are some ________ ways to loop the program. (good/bad)

(h) When you open QBASIC, you see a _______ screen where you can type your program. (green/blue)

(i) ____________ is a command that allows you or anybody else who runs the program to enter the information when the program is already running. (text or number)
