SETMODE Procedure

SETMODE Function 43

This function specifies the parameters that control a subsequent receive operation

(calls to READ or WRITEREAD). You call SETMODE function 43 to set explicitly the

parameters that control a receive operation. The section below lists the parameters

you can set.

param1

.<13>

specifies whether vertical forms-control information sent from the host is removed

from the data or translated to BSC vertical forms-control escape sequences. This

field can have the following values:

0 FORMS OFF

The vertical forms-control information sent from the host is removed from the

data before the data is passed to your program.

1 FORMS ON

The vertical forms-control information sent from the host is translated to BSC

vertical forms-control escape sequences and then passed to your program in

the first two bytes of each record. For a list of BSC vertical forms-control

escape sequences, see the RECEIVE command in Section 3. Your program is

responsible for translating the BSC vertical forms-control escape sequences

into the appropriate action.

param1

.<15>

specifies whether the data received from the host is translated from EBCDIC to

ASCII before the data is passed to your program. This parameter controls the

translation of both transparent data and nontransparent data. This field can have

the following values:

0 TRANSLATE ON

The data is translated from EBCDIC to ASCII before being returned to your

program. Use this specification to receive data from the host that is coded in

EBCDIC (assuming you want your program to receive ASCII data).

1 TRANSLATE OFF

The data is not translated from EBCDIC to ASCII before being returned to

your program. The data is returned to your program exactly as received. Use

this specification to receive data from the host that is not coded in EBCDIC.

If you do not call SETMODE function 43 before a receive operation, the receive

operation will have the following characteristics:

FORMS OFF

TRANSLATE ON
