The source format

The COMIS source code is essentially free format. Extensions are:

• Statements may start at any position.
• More than one statement may be given per source line. In this case they should be separated by blank(s), or optionally by ';'.
• A statement may occupy more than one source line without any special marks.
• Source lines may be up to 80 characters long. Thus, source line numbering in columns 73-80 is not available.
• A symbolic name is a string of letters, digits and underscore (_). The symbolic name may have any length, but significant characters are the first eight only.

Note

• Blanks are meaningful in COMIS.
• Comment lines are marked by '*' or 'C' in column one. An exclamation mark (!) starts an inline comment, except when it appears as the first non-blank character on a line.
• Some extentions may cause a conflict with the conventions of Fortran 77 (see the !FORTRAN directive in Chapter 4).
