Re: crtpgm vs crtsrvpgm

Hi rx,

CRTPGM is creates PGM object. it is runnable.
CRTSRVPGM is creates service program (SRVPGM) object. it is not runnable object.

Re: crtpgm vs crtsrvpgm

As the Name Suggests, Service program is kind of Service repository which is attached to Program if your program is inheriting some services (Like procedures, modules) which are available in a service program.

You can keep all service modules like calculations, date handlings, report headings in a service program and then use them in your program.

Re: crtpgm vs crtsrvpgm

Program:the CRTPGM command create a program object from one or more previously created modules and if required,one or more service programs.You can bind modules created by any of ILE create module commands CRTRPGMOD,CRTCMOD,CRTCBLMOD,or CRTCLMOD.
NOte: the module and service program must hav been created prior to using CRTPGM command.

Service Program: A service program is a bound program(type *SRVPGM) consisting a set of procedure that can be called procedure in other bound programs

Service Program typically used for comman function that are repeatidy called within an application and across application.

For example the ILE compilers use service programe to provide run time services such as math function,i/o routines. Service prograsm enable reuse and simplyfy maintance and reduce storage

A service Program differs from a program in two ways

1.It does not contain a PEP(program entry procedure).means that you can not call a service using the CALL operation.
2.A Service program is bound into program or other service program using binding by reference.
