AREV Specific

The user has been running version 3.12 for years. During the last week she repeatedly has gotten this message when entering data:

'CATALYST'Line 1. B28 Not enough string space - Out of Memory.

Line 1 'CATALYST' broke because a run time error was encountered..

!e037 Execution counter set to 037.

!0 invalid debugger command.

No changes have been made to her PC and there is plenty of available space on the server where the database resides.

String space is related to the amount of DOS memory on the individual PC. You might need to redefine various settings on the PC that have changed. An upgrade to a new operating system, network client, memory manager, or installation of new software might make enough changes in the system to cause this problem.

These changes could be in the changing of memory information in CONFIG.SYS, loading of new or updated drivers, or modification to the initial ARev startup command.

The Advanced Revelation FAQ has information on maximizing memory and string space.

To detect the amount of memory available to AREV use the RBASIC

lines:

DECLARE FUNCTION MEMSPACE

BYTES.FREE=MEMSPACE(999999)

Also, to reclaim memory:

@TCL.STACK='

FLUSH

GARBAGECOLLECT

Also, enable expanded memory from DOS, then run AREV.EXE with the

/XM4096 switch present on the DOS command line.

Another way to check how much free memory you have at any given time is to type WHO at TCL. Near the bottom of the screen is how much memory your PC has free.

As a general rule of thumb, we have found that 200K is the minimum you need to keep running. If you go below that you may get the "Out of string space" error. When that happens, we normally tell our users to log out and then log back in to the AREV application (we are useing AREV 3.12). The logging in will reset everything and start you fresh on memory. I know that isn't the most elegant solution but that is what we have found to work for us.

I personally haven't ever had any luck with the GARBAGECOLLECT process.
