6.2.40.1.2 LINAGE-COUNTER Rules

If the LINAGE clause is specified for this file, the associated LINAGE-COUNTER special register is modified during the execution of the WRITE statement, according to the following rules:

1.

If ADVANCING PAGE is specified, LINAGE-COUNTER is reset to 1.

2.

If ADVANCING identifier-2 or integer is specified, LINAGE-COUNTER is increased by the value in identifier-2 or integer.

3.

If the ADVANCING phrase is omitted, LINAGE-COUNTER is increased by 1.

4.

When the device is repositioned to the first available line of a new page, LINAGE-COUNTER is reset to 1.

X Note: >_Host_> If you use the ADV compiler option, the compiler adds 1
X byte to the record length in order to allow for the control character. If
X in your record definition you already reserve the first byte for the
X control character, you should use the NOADV option. For files defined
X with the LINAGE clause, the NOADV option has no effect. The compiler
X processes these files as if the ADV option were specified. <_Host_<
