Other ILE program can access the procedure in the service program Use of service program - modularity and maintainability CRTSRVPGM, UPDPGM, UPDSRVPGM CRTBNDRPG -- to contain name of modules or service program that your program or service program may use. Parameters and Prototypes A list of binding directories may specified when you create program OPM using CRTBNDRPG or ILE CRTPGM or CRTSRVPGM service prorgam. They can also be specified on the CRTRPGMOD command. A binding directory may reduce the program size because modules or service programs listed in the binding directory are used only when they are needed
