ZALLOCATE.V2 V03 14FEB89

DESCRIPTION

This program allows a way to ZALLOCATE memory in a different

part of the memory than VAL-II does. This program attempts to

get space at the end of the physical memory area, instead of

somewhere in the middle. Because of this, there is a better

chance of getting this space after programs have been loaded

into memory, than when using the VAL-II ZALLOCATE command at

this point.

PREPARATION

Load the ZALLOCATE.V2 file into memory.

PROGRAM EXECUTION

After executing the ZALLOCATE program, a check will be made

to see if this area is available or not. If the area is not

available, then the program will display a message and ABORT.

The number of words to be allocated must be entered next. If

there is not enough space to allocate this many words, then

the program will be ABORT'd.

The program then changes the internal VAL-II boundary tags so

that this area is now available for use.

NOTES

This program will work on either VAL-II 1.4 software versions

or VAL-II 2.0 versions.

MESSAGES

*** ZALLOCATE area already in use ***

This message will get displayed immediately after the program

has been executed if the area at the highest portion of the

user memory is already being used.

*** Not enough memory available ***

This message will get displayed after the amount of words are

entered. If there is not enough room for the specified number

of words, then this error occurs.
