If a STRING CONSTANT is used at the beginning of an INPUT statement, the prompt character following it can be modified using the PRMT(char) instruction. The default character is a space.
Program Example.
00100 INPUT "Please enter a number" A
00110 PRINT A
00120 PRMT(?)
00130 INPUT "Please enter a number" A
00140 PRINT A
00150 END
