When the ALGOL compiler compiles a program, it requires, at minimum, one input file that contains the source code to be compiled. If the compile is successful, the compiler produces, at minimum, one output file that contains executable object code.

Through the use of compiler control options, the compiler can be directed to use additional input files and to produce additional output files. Among the optional input files that can be used are files containing source code that is to be merged or inserted into the required source code file, and files containing information needed to perform separate compilation and binding. Among the optional output files that can be produced are a printer listing of the program, a cross-reference file, an updated source file, an error message file, and a file containing information needed for future separate compilation.

Compiler Input Files and Compiler Output Files list the logical input and output files used by the ALGOL compiler. Each file is listed with values for the INTNAME, KIND, INTMODE, MAXRECSIZE, BLOCKSIZE, and FILETYPE attributes. Some or all of the attributes for these files can be changed, using compiler file equation, when the compiler is initiated. For information on file attributes refer to the File Attributes Programming Reference Manual. For information about compiler file equation, see the Work Flow Language (WFL) Programming Reference Manual.
