INCLAN: echo

Synopsis

echo

Description

Determines which commands are echoed, i.e. copied to standard output before execution. The possible settings are:

NULL

(or not set at all) In macros, all commands except those built into the command line interpreter are echoed;interactive commands are not echoed.

off

Commands are not echoed.

on

Both in macros and interactively, all commands except those built into the command line interpreter are echoed.

large

Same as on, except that the echo is surrounded by blank lines.

full

All commands are echoed, and the corresponding line numbers in macros are given.

OFF

Same as off, except that this setting can only be overridden by another value written in capital letters.

ON

Same as on, except that this setting can only be overridden by another value written in capital letters.

LARGE

Same as large, except that this setting can only be overridden by another value written in capital letters.

FULL

Same as full, except that this setting can only be overridden by another value written in capital letters. This setting is particularly useful for debugging macros in which the echo is suppressed.

Labels are not included in the echo, but variable substitutions are. Statements preceded by “@” are only echoed if echo has the value full or FULL.
