DISP Display a Memory Area from a Foreign TSN

With a mouseclick you get a describtion of the screen item.

DISP [addr] [, L=len] [, O=offs] [, T=tsn]

The DISP command displays a memory dump in Display mask format from the task under which TAS is running, or from a foreign task, or from the system address area.

addr Hexadecimal address in the form, for example, 70000000, 12F00 or AB1C20.

12F00 and AB1C20 for example, indicate a virtual address of the current or foreign task. 70000000 indicates a system address. If no address is specified, the default address of 0 will be used.

%xxx Instead of an absolute address, the name of a system table can be specified instead:

%XVT Executive Vector Table

%TCB Task Control Block

%TET Terminal Entry Table

%JCB Job Control Block

%JTBP Job To Be Processed Block

%SVMT System Virtual Memory Table

If the table should be displayed only from a particular address, then the parameter +nn can be included after the table name to indicate the offset. nn will be interpreted as a decimal value if it contains only decimal figures. If it contains any hexadecimal figures, it will be interpreted as a hexadecimal value. +nnH will force it to be interpreted as a hexadecimal value.

To display a table from a particular position, the following command can also be used: DISP ....;Pnnn . In this case, nnn will always be interpreted as a hexadecimal value. The advantage of this variation is that any portion of the table can be displayed therafter, including the beginning of the table by entering --.

L=len Length of the address area to be displayed in decimal or hexadecimal format.

L=100 will be interpreted as a decimal length.

L=1A0 will be interpreted as a hexadecimal length.

L=100H will be interpreted as a hexadecimal length.

Standard: The area up to the end of the current 4k page will be displayed.

O=offs The specified offset will be added to addr. The resulting value is used as the starting address for the memory area to be displayed. offs must be specified in the same format as addr.

Standard: O=0

T=tsn TSN of the task whose memory should be displayed. Leading zeroes can be omitted from the TSN.

Standard: TSN of the current process.

Notes:

The DISP command can be entered from any TAS mask. This command will enable the TAS Display mode (see page ).

The DISP command can also be entered from within the Display mode. Pressing the K1 key will return the user to the screen last displayed with DISP. K13 (ESC <) or entering the command NEW will return the user directly to the Task list from any DISP level.
