Each PSK library function returns a specific status value. The PSK provides status code
macros that determine the success of the function without testing for an explicit value.
For most functions, you only need to know if the result was success or failure. Your
program is easier to maintain, update, and port to another terminal type when you check
for success or failure instead of a specific value.

This example tests for success or failure and then provides an action for each condition.

/* This segment requests label input, then checks for success */

/* If successful, then retrieve the label symbology           */

/* If an error occurred, display the error message            */

/* Request input */

status = im_receive_input(IM_LABEL_SELECT, IM_INFINITE_TIMEOUT,

&source, input);

if ( IM_ISSUCCESS(status))

im_get_label_symbology( &symbol);

if ( IM_ISERROR(status))

im_message(status);
