Hi,
I am trying to undersyand an Easytrieve program. This is quite different from Easytrieve Plus that I am used to and hence I need some help. Can someone please briefly let me know with respect to the part in bold, how this program functions?
Thanks

FILE FILEB FB-17-FULLTRK

9999

FILE TABLEFL FB-17-FULLTRK

9999

IF SORTED = YES THEN GO TO AFTERSORT

IF FILE = FILE ---à What is this condition meant for?
ARG1X = ARG1

FUNC1X = FUNC1

MOVE ARG1X 17 TO ARG

CNT*IN = CNT*IN + 1

SEQ*IN = CNT*IN

SUCCESS

IF TRAIN = ( FILL ) ---à FILL means?

SYMBOL = (FILL)

TRAIN2 = DEPDAY

IF FILE = FILE

FRCITYST = * --------------------à Asterisk indicates the function?
TOCITYST = *

IF FRCITYST = * THEN FRCITYST = CHECK FRMP ----à check FRMP means?
IF TOCITYST = * THEN TOCITYST = CHECK TOMP

IF FRCITYST = * THEN FRCITYST = RECHECK FRMP

IF TOCITYST = * THEN TOCITYST = RECHECK TOMP

IF FRCITYST = * THEN FRCITY6 = FRMP

OTHERS = OTHERS + 1

IF TOCITYST = * THEN TOCITY6 = TOMP

OTHERS = OTHERS + 1

Hello,

Which release of Easytrieve are you using (the output will show this)?

Not really sure about the release...this is a new setup againg as I said I am used to Easytrieve Plus; this seems to be an older version where statements like DISPLAY are not supported. Can someone explaing the below technical jargon in Easytrieve.

FILE = FILE means? I believe it signifies a true condition

anlso unsure what
TRAIN = ( FILL ) means?

Also unsure of the below technical jargon:-

FRCITYST = *
and
IF FRCITYST = * THEN FRCITYST = CHECK FRMP
IF TOCITYST = * THEN TOCITYST = CHECK TOMP
IF FRCITYST = * THEN FRCITYST = RECHECK FRMP

Also was trying to get hold of an older Easytrieve manual but didnt find it on net.

Hello,

You should not be able to find this on the net. . . The documentatoin is covered by copyright and it is illegal to make it publically available on some website . . .

If your organization is licensed to use the product CA support will be able to help.

Easytrieve shows the version in the output (at least all of the ones i've seen).

Suggest you experiment with the code and see what happens when you change a statement. Also suggest that you only do one exieriment at a time. . .

FRCITYST = * is the same as FRCITYST = ' '
IF FRCITYST = * is the same as IF FRCITYST = ' '

( FILL ) never heard or did see that one
CHECK/RECHECK never heard or did see those

IF FILE = FILE is the same as IF 1 = 1

the stament takes care that all statements after a previous IF are not processed because of that previous IF, e.g.

IF condition
statement 1
statement 2
statement 3
statement 4

if only statement 1 and 2 need to be executed because of the condition
then a IF FILE = FILE is needed before statement 3.

This is because the old EASYTREV program didnt have
IF ... END-IF or DO ... END-DO constructions.
