To process QSAM files in a program, a programmer could use COBOL language statements that:

After a record is created, its length or its position in the file cannot be changed, and it cannot be deleted. QSAM files can, however, be updated on DASD (using
The record definitions that are coded in COBOL program and the length of the variables read into and written from determines the amount of data transferred.
You can also access byte stream files in the HFS using QSAM. These files are byte-oriented sequential files with no record structure, modelled after those used in Unix-like and Windows systems. Such files cannot be updated using
