Example: Creating your own telephone directory
These ILE C programs show how to create a user index for a telephone directory, how to insert entries into the telephone directory, and how to find an entry.
Note: By using the code examples, you agree to the terms of the Code license and disclaimer information.
To create a user index, use the following program, $USIDXCRT:
/********************************************************************/
/* PROGRAM: $USIDXCRT */
/* */
/* LANGUAGE: ILE C */
/* */
/* DESCRIPTION: THIS PROGRAM CREATES A USER INDEX NAMED "TESTIDX" */
/* IN THE LIBRARY "QGPL". */
/* */
/* APIs USED: QUSCRTUI */
/* */
/********************************************************************/
#include <quscrtui.h>
main()
{
/********************************************************************/
/* Set up the parameters to be used in the call to 'QUSCRTUI' */
/********************************************************************/
char idx_name[]= "TESTIDX QGPL ";
char ext_atr[]= "TESTER ";
char entry_lgth_att[] = "F";
int entry_lngth = 50;
char key_insert[] = "1";
int key_lngth = 15;
char imm_update[] = "0";
char optim[] = "0";
char auth[] = "*CHANGE ";
char desc[] = "Description ..... ";
/********************************************************************/
/* Call the 'QUSCRTUI' program to create the user index. */
/********************************************************************/
QUSCRTUI(idx_name,ext_atr,entry_lgth_att,entry_lngth,key_insert,
key_lngth,imm_update,optim,auth,desc);
}
To compile the program that creates the user index, specify
CRTBNDC PGM(QGPL/$USIDXCRT) SRCFILE(QGPL/QCSRC)To insert entries into the user index, use the following program $USIDXEX:
/********************************************************************/
/* PROGRAM: $USIDXEX */
/* */
/* LANGUAGE: ILE C */
/* */
/* DESCRIPTION: THIS PROGRAM USES A USER INDEX TO KEEP TRACK OF */
/* NAMES AND PHONE NUMBERS. THERE ARE TWO OPERATIONS THAT ARE */
/* DEMONSTRATED IN THIS EXAMPLE. THE FIRST IS THE INSERTION OF */
/* AN ENTRY INTO THE INDEX, AND SECONDLY THE FINDING OF A GIVEN */
/* INDEX ENTRY. */
/* THE INDEX IS KEYED ON THE LAST NAME, THEREFORE ENTER AS MUCH */
/* OF THE NAME AS YOU KNOW AND THE PROGRAM WILL LIST ALL ENTRIES */
/* MATCHING YOUR STRING (IN ALPHABETICAL ORDER). */
/* */
/* APIs USED: NONE */
/* */
