CA-GSS/ISERV Commands › CA-GSS/ISERVE Operator Commands › DISPLAY FNTAB

DISPLAY FNTAB

Use the DISPLAY FNTAB command to display information about REXX functions that are loaded when CA‑GSS is initialized.

Syntax

Use this format for the DISPLAY FNTAB command:

Display FNTab [{External} [[+|-] {Class|Name} [[+|-] {Class|Name}]]
               {Internal}
               {Builtin}
               {All}

Parameters

The DISPLAY FNTAB command takes these parameters.

External	Lists only external functions (ones defined in the initialization parameters). This is the default.
Internal	Lists only internal (CA‑GSS extended) functions, which set the RC special variable.
Builtin	Lists only built-in functions, which are included as part of the language definition.
All	Lists all functions.
+	Sorts in ascending order. This is the default.
-	Sorts in descending order.
Class	Sorts by function class (external, internal, or built-in).
Name	Sorts by function name.

Usage Notes

You can specify up to two sort criteria. If you specify both CLASS and NAME, information is sorted by name within class.
If no sort criteria are specified, +NAME is used.

Fields in the Example

Class

Function's class, as follows:

Builtin: Function that is considered part of the language specification.
External: Processed by external load module specified in initialization parameters.
Internal: CA‑GSS extended function.

Name

Name of the function, as coded in IMODs.

Avail

Indicates whether or not the function is currently available for use by IMODs.

Module

Name of the load module that will be used to process the function.

Type

How the function executes, as follows:

ASYNC: Executes as a subtask.
SYNC: Executes under the main ISERVE task.

Address

Address in memory (hexadecimal) where the load module resides, if applicable.

Length

Length of the load module (hexadecimal) in memory, if applicable.

Rent

Indicates whether or not the load module is re-entrant, if applicable.

AMODE

Addressing mode of the load module (24- or 31-bit), if applicable.
