Turbo PMAC On-line Command Specification 356
 the optional second{constant} must be at least as great as the first {constant} -- it represents
the number of the end of the range;
 {address} is an integer constant from $000000 to $FFFFFF (0 to 16,777,215 if specified in
decimal).
This command causes Turbo PMAC to define the specified M-variable or range of M-variables to point to
a long word (48 bits) of data – both X and Y memory – at the specified location in Turbo PMAC's address
space. The data is interpreted as a floating-point value with Turbo PMAC’s own 48-bit floating-point
format.
The definition consists of the letter L, an optional colon (:), and the word address.
Memory locations for which this format is useful are labeled with 'L:' in the memory map.
Example:
M5147->L:$002047
M5148->L$02048
M5148->L8264

Function: Binary Thumbwheel-Multiplexer Definition
Scope: Global
Syntax: M{constant}[..{constant}]->TWB[:]{multiplex address},
{offset},{size},{format}
where:
 {constant} is an integer from 0 to 8191 representing the number of the M-variable;
 the optional second{constant} must be at least as great as the first {constant} -- it represents
the number of the end of the range;
 {multiplex address} is an integer constant in the range 0 to 255, representing the byte address
in the multiplexing scheme on the thumbwheel port of the least significant bit to be used in the M-
variables;
 {offset} is an integer constant from 0 to 7, representing which bit of this byte is the least
significant bit to be used in the M-variable;
 {size} is an integer constant from 1 to 32, representing the number of consecutive bits to be used in
the M-variables;
 {format} (optional) is either U for unsigned, or S for signed (two's complement). If no format is
specified, U (unsigned) is assumed.
This command causes Turbo PMAC to define the specified M-variable or range of M-variables to a
consecutive of input bits multiplexed on the thumbwheel port with Accessory 18 or compatible hardware,
including the Advantage 500 NC control panel.
Example:
M0->TWB:0,0,1
M1->TWB:0,1,1
M10->TWB:3,4,4,U
M745->TWB:4,0,16,S
M872->TWB:0,4,1
