Overview of format specifications.

Description

specifies the output display format mode of operation to use.

It precedes the address of the data to access. Once set, the 'data.format.specification' remains in the designated mode until explicitly changed and is applied to subsequent data displays which do not specify a different data format.

The 'data format specification' is one of the three elements used in referencing disk locations within the system debugger; it specifies the output format: either 'integer', 'character' (ASCII) or hexadecimal.

The data format specification is optional. If unspecified, the previous format specification is used for the current data display. If no format has been assigned, hexadecimal format is the default.

All of the following are invalid with the use of the 'a' or the 'l' commands, and will generate error messages.

'data.format.specification' options:

c Character format.

i Integer format. The maximum window specification is 6. Larger numbers give unpredictable results.

x Hexadecimal format.

w Hexadecimal Word format. This is identical to the 'x' format, but data is displayed in 2-byte words meaning that the output will be un-byte-swapped on Intel platforms. Available on 6.1.0 and above only.

Example

!x/mbase<return> <- Enter this.
!x/mbase .00017A5B= <- This displays.

!c/mbase<return> <- Enter this.
!c/mbase ...[= <- This displays.

!i/mbase<return> <- Enter this.
!i/mbase 108379 = <- This displays.
