Keeping Files Opened in RPGIII

[cannautt]

Hi everybody.

I'm developing for a customer an utility in RPGIII which accesses to several files. This ustility is an RPG program that will be called by many other programs. The problem is this: this utility will be called iterately many times(up to 100,000) even by the same program. Is there a method not to open the files used by the utility all the times, in order to improve performances?

Thanks for your help

cannautt,

In RPGIII you could not set on *INLR. This would leave the files open. You must be careful though as the variables are NOT initialized the next time the program is called. You must take care to clear everything yourself at program start up.

Hi,


I'm not sure, but if you end your programm with the "Return" instruction, the file stay opened.

Also, don't let the system to open and close files for you. The "open" and "close" allow uou to keep files opened.
