Schema Processor Commands

TurboIMAGE/XL provides several commands that you can use anywhere in the schema to

specify options available while processing the schema. The commands are: $PAGE,

$TITLE, and $CONTROL. The dollar sign ($) must always be the ﬁrst character of the record,

immediately followed by the command name, which must be completely spelled out.

If a parameter list is included with the command, it must be separated from the command

name by at least one blank. Parameters are separated from each other by commas. Blanks

can be freely inserted between items in the parameter list.

Command records cannot contain comments.

Figure 3-3. illustrates the order of commands and other input required when executing the

Schema Processor in batch mode. The job can also be stored in a disk ﬁle and executed

from a terminal.

Continuation Records

To continue a command to the next record, use an ampersand (&) as the last non-blank

character in the current record. The following record must begin with a $. The records are

combined and the $ and & are deleted and replaced by one blank character. A command

name or parameter cannot be broken by &. Characters beyond the 72nd character of each

record are ignored.
