3.5.4 format in READ and WRITE

The format, which can appear in READ and WRITE commands, specifies output format control. The parameters of format are processed one at a time, in left-to-right order.

    format::=





!
#




!
#


... [ ? intexpr ]

? intexpr




See also the transition diagram for format.

The parameters, which need not be separated by commas when occurring in a single instance of format, may take the following forms.

 !  causes a "new line" operation on the current device. Its effect is the equivalent of writing CR LF on a pure ASCII device. In addition, $X is set to 0 and 1 is added to $Y.
# causes a "top of form" operation on the current device. Its effect is the equivalent of writing CR FF on a pure ASCII device. In addition, $X and $Y are set to 0. When the current device is a display, the screen is blanked and the cursor is positioned at the upper left-hand corner.
? intexpr produces an effect similar to "tab to column intexpr". If $X is greater than or equal to intexpr, there is no effect. Otherwise, the effect is the same as writing (intexpr - $X) spaces. (Note that the leftmost column of a line is column 0.)
