#pragma margins/nomargins
Category
Purpose
Specifies the columns in the input line to scan for input to the compiler.
Syntax
Defaults
margins(1,72) for
fixed-length records. nomargins for variable-length records. 
nomargins for all records. 
Parameters
- margins
- Specifies that only text within a range of margins, specified
by first_column and last_column,
is to be scanned by the compiler. The compiler ignores any text in
the source input that does not fall within the range. Specifying margins with
no parameters is equivalent to margins(1,72) for both fixed
or variable length records.
- nomargins
- Specifies that all input is to be scanned by the compiler.
- first_column
- A number representing the first column of the source input to be scanned. The value of first_column must be greater than 0, less than 32761, and less than or equal to the value of last_column.
- last_column
- A number representing the last column of the source input to be
scanned. The value of last_column must be
greater than the value of first_column,
and less than 32761.
You can also use an asterisk (*) to indicate the last column of the input record. For example, if you specify #pragma margins (8, *), the compiler scans from column 8 to the end of input record.
Usage
The pragmas override the MARGINS or NOMARGINS compiler options. The setting specified by the #pragma margins directive applies only to the source file or include file in which it is found. It has no effect on other include files.
You can use #pragma margins and #pragma sequence together. If they reserve the same columns, #pragma sequence has priority and it reserves the columns for sequence numbers. For example, assume columns 1 to 20 are reserved for the margin, and columns 15 to 25 are reserved for sequence numbers. In this case, the margin will be from column 1 to 14, and the columns reserved for sequence numbers will be from 15 to 25.
