B (Base)

(KMON)

Sets a relocation base used to calculate the address of the location to be referenced

in a subsequent Examine or Deposit command. RT–11 adds this relocation base to

the address you specify.

Format

B [address]

Parameter

[address]

Speciﬁes an octal address that RT–11 uses as a base address for subsequent

Examine and Deposit commands. If the address you supply is an odd number,

RT–11 decreases it by one to make the address even. If you do not specify an

address, this command sets the base to zero.

Description

Use the B command when using the Examine and Deposit commands to reference

linked modules that you have loaded into memory with the GET command. (Note

that the B command has no effect on program execution.) RT–11 adds the current

base address to the value you supply in an Examine or Deposit command. You can

set the current base address to the address where a particular module is loaded.

Then you can use the relocatable addresses printed in the assembler, compiler, or

map listing of that module to reference locations within the module.

Examples

1. The following command sets the base to 0:

2. The next two commands both set the base to 1000:

.B 1000

.B 1001
