DCSTA - Generate operand table for terminal attributes

&pagelevel(3)&pagelevel

General

Application areas:

Requesting and accessing lists and tables; see "Requesting and accessing lists and tables"Input/output; see "Input/output"

Macro type:

Type O; see "O-type macros"


  • The description applies to VTSU V13.3A

Macro description

The DCSTA macro (Data Communication STation Attributes) supports the TSTAT macro. DCSTA is used to generate receiving fields or symbolic field names (DSECT) for the information supplied by the TSTAT macro.

Macro format and description of operands

[name] DCSTA

D / C

[,prefix]

,TYPE=TCHAR / PHDIM / LIDIM / VDT[YP] / EDOPT / OFLOW / STNAM / PRNAM / ALL / MONCS /

PERPH / BASIC

name
Becomes the symbolic name for the first DS statement in the macro expansion if the C operand is specified (the length attribute is zero).
If the D operand is specified, the “name” operand specifies the name of the dummy section (DSECT).

If the “name” operand is omitted, the system forms a name from the valid prefix (see the “prefix” operand) and the operand value for TYPE.

C
A storage area with symbolic addresses is generated. In the TSTAT call, this area may be specified as receiving field. No CSECT statement is generated.

D
A dummy section (DSECT) is generated together with a DSECT statement. The symbolic name generated can be used to address a receiving field previously defined for the TSTAT macro.

prefix

The prefix may consist of 1 to 3 characters, which are to appear at the beginning of the generated field names. The specified prefix replaces the characters “STA”, the default value for the field name prefix.

TYPE=
Specifies which receiving field or which field names are to be generated:

TCHAR
Requests data terminal characteristics.

PHDIM
Requests physical data terminal characteristics.

LIDIM
Requests logical data terminal characteristics.

VDT[YP]
Requests logical data terminal type.

EDOPT
Static edit options.

OFLOW
Requests overflow control type values.

STNAM
Requests data terminal name.

PRNAM
Requests processor name.

ALL
Requests information from TCHAR to PRNAM.

MONCS
Description of monitor and character sets.

PERPH
Requests connected peripherals.

BASIC
Basic information on the data terminal.

Functional description

If the TSTAT macro is used to request information, the receiving field may be defined either explicitly or with the DCSTA C,... macro. If the receiving field has been explicitly defined, the DCSTA D,... macro may be used to generate a dummy section (DSECT), i.e. an address structure for the receiving field, by means of a USING statement. In order to interrogate bit values, the DCSTA macro generates symbolic constants with which the field contents may be compared.

The field names which DCSTA generates by default may be seen in the macro expansion in the example. All of them start with the letters STA. Any string may be selected to replace these characters.

The start addresses of the receiving fields generated by the DCSTA C,... macro must be specified in the TSTAT macro.

The default start addresses are as follows:

STATCHARSTASTNAMSTAPHDIMSTAPRNAMSTALIDIMSTAALLSTAVDTSTAMONCSSTAEDOPTSTAPERPHSTAOFLOWSTABASIC

Return information and error flags

R15:

+---------------+
|   |   |   |   |
| | | | | | |a|a|
+---------------+

A return code relating to the execution of the macro DCSTA is transferred in the rightmost byte of register R15.

Return code

Meaning

X'00'

Normal termination

X'04'

Unrecoverable error

X'08'

Error in the operand list

X'0C'

No participant data terminal available

X'10'

Length of the receiving field is too short: only part of the information was given when
the operand ALL was output.
In all other operands no information is transferred.

X'14'

The desired information is (partly) not available

  • BASIC: Basic information on the data terminal (area length: 24 bytes)

Information is given in the status message from the data terminal, when this is available, otherwise it is supplied from the generation or VTSU-B default values are assumed.

If you specify a length greater than 24 and less than 33 bytes, information is only returned for bytes 0-23.

If you specify a length of 33 bytes, information is only returned for bytes 0-32. If XHCS is not loaded or if the terminal does not support extended character sets, no information is supplied on the terminal type and the extended standard name.

If you specify a length greater than 33 bytes and less than 52 bytes and the data display terminal works in 8-bit mode, the first byte of this area is set to X'00'. The information received is truncated because the specified area is too small.

If you specify a length of 52 bytes, information is returned only for bytes 0-51. Bytes that are not required are set to X'00'. No information is provided for printers.

If you specify a length of 60 bytes, information is returned for bytes 0-59. Bytes that are not required are set to X'00'.
