#INPUT Built-In Function

Use #INPUT to read information from the TACL IN file.

option

is an option that qualifies the read operation. It can be any of these:

CURRENT

reads input from the current IN file (if #IN was pushed), rather than from the

primary IN file.

FUNCTIONKEY variable-level

sets variable-level to the name of the function key used to terminate

reading. If the RETURN key terminates reading, variable-level is cleared.

Specify variable-level as the name of an existing variable level. When

this option is in effect, text generated by a function key is removed from the

input text.

HISTORY history-prompt

adds the line read to the history buffer. In addition, the history number and

history-prompt are appended to prompt.

HISTORYV variable-level

adds the line read to the history buffer. In addition, the history number and the

value of variable-level are appended to prompt.

NOECHO

suppresses echoing of the input line.

UNTIL { EOF | TACL }

specifies the conditions that terminate reading:

EOF

reads input until end-of-file is reached or, if you specify the

FUNCTIONKEY option, until a function key is pressed.

TACL

reads input until all square brackets balance. While #INPUT is reading

data, it processes function keys immediately and removes comments in the

usual TACL manner.

#INPUT [ / option [ , option ] ... / ] [ prompt ]
