2. Create a log file, if necessary.

Unless

LOGFILE(*NONE),

there

must

be

a log file for the

sion Aid to access. If you

do

not

have

one,

then

you

see

“The

Log

File”

on

page 381

and

“Using

the

Log

File” on

page 396.

3. Create the file for the converted source members.

The	Conversion Aid will not create any files. You must create					the	o
the	converted source prior	to running the CVTRPGSRC command. The				recom-
mended name and record length for the			output	file is	QRPGLESRC	and 1
characters respectively. For		additional	file	information	see “File		Cons
on	page 380.

4. Convert your source using the CVTRPGSRC command.

You need to enter the name of the file and member to be convert accept the defaults, you will get a converted member in the file The name of the member will correspond to the name of the unconvert source member. /COPY members will not be expanded in the converted member, unless it is of type RPT or RPT38. A conversion report will ated.

See “The CVTRPGSRC Command” on page 383 for more information.
