Structure of Program Segments 

Segment-Numbers 

Section classificationis accomplished by means of a system of
segment-numbers.  The segment-numberis included in the section header.

General Format.   


            

Syntax Rules.   

   1.  The segment-number must be an integer ranging in value from 0
       through 99.

   2.  If the segment-number is omitted from the section header, the
       segment-number is assumed to be 0.

   3.  Sections in the declaratives must contain segment-numbers less
       than 50.

   4.  For OSVS and VSC2 only:  The segment-number must be a signed
       integer, but must not be a floating-point literal.

General Rules.   

   1.  All sections which have the same segment-number constitute a
       program segment.  All sections which have the same segment-number
       need not be physically contiguous in the source program.

   2.  Segments with segment-number 0 through 49 belong to the fixed
       portion of the object program.

   3.  Segments with segment-number 50 through 99 are independent
       segments.

Segment-Limit 

General Format.   

The SEGMENT-LIMITclause appears in the OBJECT-COMPUTER paragraph and has
the following format:


            

Syntax Rule.   

Segment-numbermust be an integer ranging in value from 1 through 49.

For MF only:  General Rule.   

The SEGMENT-LIMIT clause is treated as documentary.
