4.4.7 Deleting a MACRO

The

ERASE

command is included to delete a

MACRO

. It can simply be

re-defined as a new

MACRO

with null commands. This method, however,

will still require the 127 byte memory allocation. A better way is to ERASE

it from memory. This un-allocates memory assigned to the

MACRO

. An

ERASE

command without parameters will clear all

MACRO

buffers. Type the

following…

The Micro488/EX will respond with…

TIME

ENDM01

Type…

ERASE 1

The Micro488/EX will respond with, as a result of the programs

ERROR

DOMACRO

command, the following error status…

C 10 G0 I S0 E06 T0 C0 NO MACRO

4.4.8 Saving the LOG Buffer to Disk
