Zbex provides escape sequences which control parameters of the display from with a Zbex program. Use putc to send these sequences to Dmuse.

== Multiple character sequences ==

=== Cursor Addressing ===

1. Relative addressing: move cursor to <x,y> position in the currently displayed screen. The <x> position in this case is actually absolute, i.e., same as <c> below. Numbering starts with 0, not 1. Numbers connected to "Y" must have at least two digits. (e.g., 09 = 9).

<esc>&a <column number> x <row number> Y
<esc>&a <column number> X
<esc>&a <row number> Y

2. Absolute addressing: move cursor to <c,r> position in the currently displayed window. Scrolling works, but you cannot move to a row below the data at the bottom a window. Numbering starts with 0. Numbers connected to "R" must have at least two digits. (e.g., 09 = 9).

<esc>&a <column number> c <row number> R
<esc>&a <column number> C
<esc>&a <row number> R

3. Cursor Relative Addressing: move cursor a relative distance from its present location <+or-c,+or-r> on the screen.

<esc>&a <+or-><column number> c <+or-><row number> R
<esc>&a <+or-><row number> r <+or-><column number> C
<esc>&a <+or-><column number> C
<esc>&a <+or-><row number> R

Note: Actually, it is possible to mix and match any of these commands. The end of the sequence is signified by a capital command letter. This means that if we want to back up the cursor 20 positions and goto row 0, we would send the command <esc>&a-20c00R
