No danger there, Rob - no mention of Input Primary in the article.
The article IS from 1993, so it won't have the newest stuff. I have a feeling that the techniques classified as having a large impact would not have so much of one today, with the new hardware. Nonetheless, some things still seem useful.
There are also things like binary vs. packed - those distinctions might change completely now - at one time, everything, it seems, was converted to packed for calculations.
Oh yeah, nothing about integer data types - only binary.
And now we have direct IO using data structures, which could be significant.
Hey, the writer may have had only a D02, and he/she did not have subprocedures, apparently - no mention.

This list is for general operating system type questions and whatnot. For
RPG specific questions please take that to the RPG400 list.
I am sure that the members on this list sure don't want to hear another
debate on the pros/cons of Input Primary files.
