page
Sets or retrieves the page width or length.
Synopsis
#include <imsl.h>
void imsl_page (Imsl_page_options option, int *page_attribute)
Required Arguments
imsl_page_options option (Input)
Option giving which page attribute is to be set or retrieved. The possible values are:
option | Description |
IMSL_SET_PAGE_WIDTH | Set the page width. |
IMSL_GET_PAGE_WIDTH | Retrieve the page width. |
IMSL_SET_PAGE_LENGTH | Set the page length. |
IMSL_GET_PAGE_LENGTH | Retrieve the page length. |
int *page_attribute (Input, if the attribute is set; Output, otherwise)
The value of the page attribute to be set or retrieved. The page width is the number of characters per line of output (default 78), and the page length is the number of lines of output per page (default 60). Ten or more characters per line and 10 or more lines per page are required.
Example
The following example illustrates the use of
imsl_page to set the page width to 40 characters. The IMSL function
imsl_f_write_matrix is then used to print a 3
× 4 matrix
A, where
aij =
i +
j∕10.
#include <imsl.h>
#define NRA 3
#define NCA 4
int main()
{
int i, j, page_attribute;
float a[NRA][NCA];
for (i = 0; i < NRA; i++) {
for (j = 0; j < NCA; j++) {
a[i][j] = (i+1) + (j+1)/10.0;
}
}
page_attribute = 40;
imsl_page(IMSL_SET_PAGE_WIDTH, &page_attribute);
imsl_f_write_matrix("a", NRA, NCA, (float *)a, 0);
}
Output
