Greg Ow #1 / 4	QB4.5 >64K Just a quick question for a friend. He is programming in QB4.5 and has reached a 64k program size limit. Is there a way around this? Modules? Linking? Any help appreciated. -- --- pacifier.com - Vancouver's Public access Internet (360) 693-0325 telnet or dial the above and type "new" at the prompt to register

COAS #2 / 4	QB4.5 >64K I was once programming a rather large application and found that I could get around the 64k problem with some limited success. I think that there is some kind of command line switch that you can use. you type at the prompt "qb /AH" or something like that and it allows you to have larger programs. You can find out exactly what the switch is by checking the help file. I say it worked with limited success because weird stuff would happen to my program. One time the editor gave me the error 'out of stack space' during the middle of my program and when I returned to edit mode all of the spots where variable names should have been just had blank spaces or garbage characters! I just made sure to save a lot and everything worked fine. Nick Martin Quote: > Just a quick question for a friend. He is programming in QB4.5 and has > reached a 64k program size limit.

Actually, this is not correct. The /AH command line option (which stands for Array Huge) allows you to dimension arrays that will hold more than 64k of data. Just thought I'd set the record straight. -Jesse -- ==================================== Very funny Scotty! Now beam down my clothes! ====================================

Just to add a bit to what Jesse said. The /AH option will allow arrays to be larger than 64k, but if one wants the array to be able to go on past 128k the the array elements must be of a size that is an even multiple of a power of 2 ie: 2,4,8,16 ... bytes. It's no problem with straight numeric arrays ie: integer, single, double, etc. as they meet the above criteria. But if it's a string array or a user defined type then the string length or the total size of the user type must be an even power of 2. It can be a real waste of space if for example you need an array of 33 byte fixed length strings. In a case like that you have to pad the strings to 64 bytes to to meet the power of 2 requirement, so you waste 31 bytes for each string. -- Bangor, Pa. USA
