In Visual COBOL, you can only specify segment numbers in the range 0 to 99 inclusive, which conforms to segment number limit specified in the ANS X3.23-1985 COBOL standard. In RM/COBOL, you can specify segment numbers greater than 99.
If your source code has segment numbers greater than 99, recode the program. Make sure that any new segment numbers you allocate do not clash with an already existing segment number. Segment numbers between 0 and 49 inclusive are used by Visual COBOL to indicate fixed portions of your object program, while segment numbers 50 to 99 inclusive indicate independent segments.
For details on the use of segmentation and segment numbers in your source programs, see COBOL Language Reference in the product Help.
