'BI' Begin Input Transparency

	Editing or Behaviour
Description	Use 'BI' to begin input transparency mode. (All input is accepted without any system interpretation of control codes. With 'BI' activated, a SIZ= option on an INPUT directive is the only way you can specify a terminator / end of input. To end input transparency mode, use the 'EI' Mnemonic.
Example	When you need to return input one character at a time, we recommend that you use the 'ME' Mnemonic. However, it is also possible to use 'BI' in combination with SIZ=1 to return input one character at a time. Then, each character is returned as entered. Standard characters are returned in the variable specified (e.g., CHAR$, below). Function and edit keys are returned in the system variable CTL. Your program will still be responsible for processing all the edit keys.   0010 INPUT (0,SIZ=1) 'BI', CHAR$, 'EI' ! This will echo the data 0010 OBTAIN (0,SIZ=1) 'BI', CHAR$, 'EI' ! This will not echo
