FOR [EACH] fname statement
Fname is the internal file name declared earlier. Statement can be any valid statement as described in the beginning of the section on statements. Notice that only a single statement is allowed, however. For this reason, in order to process multiple statements for records accessed via the FOR statement, either the compound statement must by used, or a procedure must by called.
Any nonunique field references in statement will be resolved using fname.
The FOR statement is used to read all of the records from a file and to execute a statement for each record read. If the last operation done on the file was a SELECT, the FOR statement will read the records returned by the SELECT. If a SELECT has not been done on the file, or if a FOR statement has already been done after the last SELECT, each active record in the file will be read.
Breaks and totals are handled automatically. The order of processing is:
Repeat until EOF
Read the next record
If end of file
process end of field breaks
If not the first record
Check for end-of-field breaks
Store new values
Check for start-of-field breaks
