File Specifications

A complete file specification consists of a file name optionally preceded by a pathname that specifies a directory. The pathname can be in one of two forms:

Directory names and file names should not contain any operating system wildcard characters (such as *, ?, and the [ ] construct). You can use the tilde (~) character as the first character in a pathname to refer to a top-level directory as in the C shell.

When specifying files, keep in mind that trailing and leading blanks are removed from character expression names, but not from Hollerith (numeric array) names.

File names are case-sensitive and can consist of uppercase and lowercase letters. For example, the following file names represent three different files:

myfile.for

MYfile.for

MYFILE.for
