What is static call in COBOL?

When you use the CALL literal statement in a program that is compiled using the NODYNAM and NODLL compiler options, a static call occurs. With these options, all CALL literal calls are handled as static calls. With static calls statement, the COBOL program and all called programs are part of the same program object.

What is static call?

A static call is the preferred method if your application does not require the services of the dynamic call. Statically called programs cannot be deleted using CANCEL , so static calls might take more main storage. If storage is a concern, think about using dynamic calls.

What are the static and dynamic calls in COBOL?

A static call is specified withe a CALL LITERAL, and the program is compiled with COBOL NODYNAM option. A call to the subprogram at the time of exectution (run time) is called Dynamic call. Dynamic call uses less CPU time, memory required can be less. Degrades performance.

What is a dynamic call?

When sub-program is modified, sub-program and all its calling (main) program needs to be recompiled. When sub-program is modified, only sub-program needs to be recompiled. Sub-programs are link-edited(merged) with calling program during compilation of calling program.

How do you change a static call to a dynamic call in COBOL?

For COBOL-DB2 programs you can easily convert static calls to dynamic without even modifying your code. Use DYNAM compiler option to compile your cobol code. It will itself covert all the static call into dynamic calls. This way you could be sure of dynamic calls if your code compiles successfully.

What is 77 level used for in COBOL?

Level 77 is a special level number in COBOL which is used to declare independent data items; they are not subdivisions of other data items and are not subdivided themselves. In earlier days there were differences in storage and processing of level 77 and level 01 elementary data items.

What is Ssrange and Nossrange in COBOL?

SSRANGE is a compiler option that handles the array overflow. SSRANGE also needs to be specified in COBOL programing language. These help in finding the subscript out of range. NOSSRANGE is used for performance-sensitive applications.

What is dynamic and static call?

A static call is a call to a subroutine that is statically linked into the binary executable found in the steplib or joblib (using IBM JCL nomenclature here). A dynamic call is a call to a variable name that is resolved into a program name (and possibly a location or path) at runtime.

What is static call and dynamic call?

Static Call occurs when a program is compiled with the NODYNAM compiler option. A static called program is loaded into storage at compile time. Dynamic Call occurs when a program is compiled with the DYNAM and NODLL compiler option. A dynamic called program is loaded into storage at runtime.

What is Dynam and Nodynam in COBOL?

For COBOL programs that have EXEC SQL statements, your choice of the compiler option DYNAM or NODYNAM depends on the operating environment. When you run under: TSO or IMS: You can use either the DYNAM or NODYNAM compiler option. Note that IMS and DB2 share a common alias name, DSNHLI, for the language interface module.

What is 88 level used for in COBOL?

Level 88s are used to assign names to values at execution time. Thus, a condition-name is not the name of an item, but rather the name of a value. A level 88 doesn't reserve any storage area. Each level 88 must be associated with a data item and must immediately follow that item in the Data Division.

What is soc7 Abend?

S0C7 abend is a Data exception which is caused when a usage computational-3 field has an invalid data (which is not 0-9). It may also be caused if the last byte contains an invalid sign bit (which is anything other than f, c, or d)

Why comp is used in COBOL?

COBOL has what you might call "decimal-binary" fields (COMP and siblings). That is, the data is stored as binary but its maximum and minimum values are the number and full value of the PICture clause which is used in the definition. COMP PIC 9 - can contain zero to nine. COMP PIC S99 - (signed) can contain -99 to +99.

What is subroutine in COBOL?

Cobol subroutine is a program that can be compiled independently but cannot be executed independently. There are two types of subroutines: internal subroutines like Perform statements and external subroutines like CALL verb. Call Verb. Call verb is used to transfer the control from one program to another program.

What is link edit in COBOL?

A link edit part containing linkage editor control statements must be defined for each generated program that contains static COBOL calls. The linkage editor control statements consist of ENTRY and NAME statements for the load module and INCLUDE statements for each statically called program and the base program.

What is linkage section in COBOL?

The Linkage Section describes data made available from another program through the CALL statement. It can also be used to describe the format of data accessed by using the ADDRESS OF special register.

What is Call by reference in COBOL?

BY REFERENCE means that any changes made by the subprogram to the variables it received are visible by the calling program. BY CONTENT means that the calling program is passing only the contents of the literal or identifier .

What is the difference between include and copy in COBOL?

The only difference between INCLUDE and COPY is that while INCLUDE is executed at pre-compile time (by the SQL compiler), COPY is executed at compile time(by the COBOL compiler).

How do you call a subprogram in COBOL?

In COBOL, there are three ways of transferring control to a subprogram. In the first form, the called subprogram is specified as an alphanumeric literal. In the second form, name refers to the COBOL data area with length equal to that required for the name of the subprogram.

What is the difference between next sentence and continue in COBOL?

NEXT SENTENCE gives control to the verb following the next period. CONTINUE gives control to the next verb after the explicit scope terminator. (This is not one of COBOL II's finer implementations).

How can you tell if a program is static or dynamic?

The ONLY way is to look at the output of the linkage editor (IEWL) or the load module itself. If the module is being called DYNAMICALLY then it will not exist in the main module, if it is being called STATICALLY then it will be seen in the load module.

What is offset in COBOL?

The Length or Offset of the data item measured in 1-byte increments. The offset origins start at 1, unlike with other languages in which offsets might start at 0. The table item is not a data item, but some other string, such as a program label or paragraph name.

What is on size error in COBOL?

In Visual COBOL, the ON SIZE ERROR condition exists when the value resulting from an arithmetic operation exceeds the capacity of the specified picture-string. In RM/COBOL, the ON SIZE ERROR condition exists when the value resulting from an arithmetic operation exceeds the capacity for the associated data item.

What is compiler listing in COBOL?

For COBOL programs, up to and including Enterprise COBOL V4, but excluding VS COBOL II, the compiler listing data set name is obtained from debug information in the load module, placed there by the compiler. In this case, the date and time in the listing are checked against the compile date and time in the load module.
