character
During a PROMPT or READ instruction, all control characters are ignored except those listed
above. Tab characters are automatically converted to the appropriate number of space
characters when they are received. (Tab stops are assumed to be set every eight spaces [at
columns 9, 17, 25,...] and cannot be changed.)
Unlike PROMPT, both READ and GETC require that the terminal be ATTACHed.
Normally, READ and GETC echo input characters as they are processed. An optional mode
argument for each of these operations allows echo to be suppressed.
Output Processing
Output to the system terminal can be performed using PROMPT, TYPE, or WRITE
instructions. All eight-bit, binary, byte data is output to the terminal without any
modification.
TYPE and WRITE automatically append a Return character (13 decimal) and Line Feed
character (10 decimal) to each data record, unless the /S format control is specified. PROMPT
does not append any characters.
Unlike all the other I/O devices, the terminal does not have to be attached prior to output
requests. If a different task is attached to the terminal, however, any output requests are
queued until the other task detaches. V+ system error messages are always displayed
immediately, regardless of the status of terminal attachment.
