infds主要是用于对文件状态的一个管理,其相关的信息如下:
File Information Data Structure
A file information data structure (INFDS) can be defined for each file to make file exception/error and file feedback information available to the program. The file information data structure, which must be unique for each file, must be defined in the main source section. The same INFDS is used by all procedures using the files.
what ibm says:
The INFDS contains the following feedback information:
File Feedback (length is 80)
Open Feedback (length is 160)
Input/Output Feedback (length is 126)
Device Specific Feedback (length is variable)
Get Attributes Feedback (length is variable) * Standard RPG feedback area 1-80
