I admit tp having gone back and edited a post of mine that I made a few days ago and changed File to Data Set. I realise we all know what is meant when one writes 'file' but we are supposed to be professionals and our jobs are to get things right so we should strive to get our terminology right.
Recently I was reviewing my PL/1 tutorial from IBM. Here are a couple of extracts from the introduction to RECORD INPUT/OUTPUT...
o Data held externally to a program is held in data sets.
o External data is represented in a PL/1 programby a FILE. The actual data set to be processed is defined by JCL thus a program can be used to process different data sets without modification, so long as etc etc
What this means is that, for PL/1 anyway, a file is the DDName used and Data set is the actual data allocated to that DDname.
The manual did not go into whether it is Pea Ell One or Pea Ell Eye but within IBM I was told it stood for Programming Language One.
