insufficient virtuell memory during open statement

[tropfen]

Hello,

i came across a strange behavior i can not understand.

i have a application using 767660K virtual memory (according to the task manager). I would like to open a file using the following statement:

open( 10,file=..., access="direct",recl=192690800,action="read")

At this statement the programm stops showing the error:

forrtl: severe(41): insufficient virtual memory

Does a open statement need any additional memory?

I have the following pc configuration
WIN XP Prof
2GByte RAM
IVF 10....26
VS2005 German

thanks in advance for any help.

Yes, OPEN, and many other run-time functions, grab a little more dynamic memory (maybe a great deal, for such an abnormally large recl value).

Thanks for the information.

what size of memory is needed? How can i calculate the needed size?

Thanks in advance

The RTL allocates a buffer the size of the record specified, which for an unformatted file is RECL*4, unless you also set /assume:byterecl.
