ABAP/4 stands for Advanced Business Application Programming is the programming language used for the thousand of tiny embedded programs called transactions that make up the SAP application. 

ABAP programs are objects of the R/3 Repository. Like all other Repository objects, you maintain them using an ABAP Workbench tool - in this case, the ABAP Editor (tcode SE38).
