I frequently use single letter control variables in short DO loops. But my primary criterion is legibility.

I stopped using FORTRAN style single character variable names when I started coding in REXX. Except I do use them on occasion for building large stem variable lists. example:- i=i+1;jcl.i="//BRUCESMP JOB (1234546),'Bruce SMP jobn'," i=i+1;jcl.i="// CLASS=A, " i=i+1;jcl.i="// MSGCLASS=X, " i=i+1;jcl.i="// MSGLEVEL=(1,1), " i=i+1;jcl.i="// NOTIFY=&SYSUID " i=i+1;jcl.i="//* " So many ways to use REXX.
