The INSERT statement (under the BASIS mechanism) lists lines of COBOL source
to be included in the program submitted to your COBOL system.
General Format

The INSERT reserved word can commence anywhere between columns 1 and 66 of
the statement line.
Subject-sequence must be a positive numeric integer (following the rules
for integer numeric literals).
General Rules
Subject-sequence refers to that statement within the COBOL source file after
which the COBOL statement(s) is to be included.
All the COBOL statements following the INSERT statement in the edit control
file up to the next BASIS mechanism DELETE or INSERT statement are included
in the source submitted to your COBOL system. At least one COBOL statement
must immediately follow the BASIS mechanism INSERT statement.
