HOST FORMS DESCRIPTION LANGUAGE
If you omit optional keywords and system defaults, the
short form of the command looks like this example:
AT 7 14 LINES –1 TO 132 EVERY 4;
2. Draw 15 parallel vertical lines as shown.
-1 4 12 39 48 55 64 72 79 87 96 104 112 121 132
7
59
This example shows the long form of the LINE command:
AT –1 DRAW VERTICAL LINES FROM 7 TO 59 USING SOLID
1 AND REPEAT HORIZONTALLY AT 4, 12, 39, 48, 55, 64, 72,
79, 87, 96, 104, 112, 121, 132;
The LINE command draws lines in a vertical direction,
beginning at character position –1 and repeated at the
specified intervals, with each line extending from character
row 7 to character row 59. HORIZONTALLY is the default
direction of the repetition process when printing is vertical.
The following example, which omits optional keywords and
system defaults, is the short form of the command:
AT –1 VERTICAL LINES 7 TO 59 AT 4, 12, 39, 48, 55, 64, 72,
79, 87, 96, 104, 112, 121, 132;
3. Use the BOX command to draw an invisible box and center
it above the table.
This example shows the long form of the command:
AT 2, –1 DRAW 1 BOX 133 WIDE BY 5 HIGH USING SOLID
0;
The BOX command draws an invisible box 133 grid units
wide by 5 grid units high under character row 2, beginning
two character positions to the left of character position 1.
Use SOLID 0 as the thickness of the box line when you
want to draw an invisible box. Notice that the horizontal
sides of the box begin and end at the same character
positions as the horizontal lines of the table.
This example shows the short form of the command:
AT 2, –1 BOX 133, 5 SOLID 0;
