SETMODE function 144 Procedure

The SETMODE function 144 procedure is used in a SNAX environment to find the

single-byte character set and double-byte character set (if any) defined for the logical

unit (LU). In an TN3270e server environment, SETMODE function 144 returns hard-

coded values for the Katakana (single-byte) and Kanji (double-byte) character set

codes. If the -k command line option is not selected, the single-byte character set code

returned is 9 for EBCDIC. The double-byte character set code is 0, indicating no

double-byte character set is used. If the -k option is selected, the single-byte character

set code returned is 14 for Katakana EBCDIC. The double-byte character set code is 3

for IBM MIXED.

SETMODE function 144 also returns a value indicating the IBM device type. The

TN3270e server does not hard-code this value. The IBM device type code returned

depends on which IBM terminal emulation is selected for the window during Telnet

terminal type negotiation. If the -k option is selected, a value of 2 is returned, indicating

that the terminal is not a 3277 or 3276.

filenumber

INT:value

is the file to receive the SETMODE function.

144

INT:value

is the SETMODE function for obtaining the character set.

last-params

INT .ref:2

is a value that must be provided. It is used to contain output parameters.

last-params [0].<0>

always contains a 1 indicating that the TN3270e server does ASCII/EBCDIC

translation.

CALL SETMODE (filenumber, 144,,, last-params);
