Syntactic Variables

The syntactic variables shown below are encountered in the command descriptions on the following pages. In addition, other syntactic variables may be used and are defined in the particular command description in which they occur.

del Delimiter; either a comma or a space.

exp Expression (described in detail in a following section).

addr Address (described in detail in a following section).

count Count; the syntax is the same as for exp.

range A range of memory addresses which may be speciÞed either by addr del addr or by addr: count.

text An ASCII string of up to 255 characters, delimited at each end by the single quote mark (').

Expression as a Parameter

An expression can be one or more numeric values separated by the arithmetic operators: plus (+), minus (-), multiplied by (*), divided by (/), logical AND (&), shift left (<<), or shift right (>>).

Numeric values may be expressed in either hexadecimal, decimal, octal, or binary by immediately preceding them with the proper base identifier.

Base	IdentiÞer	Examples

Hexadecimal	$	$FFFFFFFF

Decimal	&	&1974, &10-&4

Octal	@	@456

Binary	%	%1000110

If no base identifier is specified, then the numeric value is assumed to be hexadecimal.
