A range of memory can be modified such that the content of each location in the
range is changed to the single specified value, or to a single or repeated sequence.
This type of memory modification is done by entering the limits of the memory
range to be modified (--EXPR-- thru --EXPR--) and the value or list of values
(--EXPR--, ... , --EXPR--) to which the contents of all locations in the range are to
be changed.
Note that if the specified address range is not large enough to contain the new data,
only the specified addresses are modified.
If the address range contains an odd number of bytes and a word operation is being
executed, the last word of the address range will be modified. Thus the memory
modification will stop one byte after the end of the specified address range.
If an error occurs in writing to memory (to guarded memory or target memory with
no monitor) the modification is aborted at the address where the error occurred.
For integer memory modifications, the default is to the current display memory
mode, if one is in effect. Otherwise the default is to "byte."
For real memory modifications, the default is to the current display memory mode,
if one is in effect. Otherwise the default is "word."
The parameters are as follows:
bytes Modify memory in byte values.
--EXPR-- An expression is a combination of numeric values, symbols, operators, and
parentheses, specifying a memory address. See the EXPR syntax diagram.
FCODE
The function code used to define the address space being referenced. See the
syntax diagram for FCODE to see a list of the function codes available and for an
explanation of those codes.
long Modify memory values as 32-bit long word values or 64-bit real values when
preceded by real.
real Modify memory as real number values.
<REAL#>
This prompts you to enter a real number as the value.
short
Modify memory values as 32-bit real numbers.
words Modify memory values as 16-bit values.
string
Modify memory values to the ASCII character string given by <STRING>.
