The Built-in Software
Example:
CENTER
Tells the printer to print the current line centered on the page. Type the
CENTER instruction at the beginning of the line you want to center, then type the
text right next to the CENTER instruction. Do not try to center the text on the
screen; the centering is done when the document is printed.
center;
. HISTORY OF COAL MINING Prints the title centered on the
page.
EOF?
Lets you get data from more than one file manager record in a continuous print
operation. EOF? (End Of File?) creates a conditional loop that goes through a file
to get field data from a series of records. Then the document is reprinted for each
record.
Use the EOF? instruction when you want to print multiple copies of the
document with data from a sequential group of records. For example, you would
use EOF? to print form letters, address lists, labels, and so on.
The EOF? instruction, which must be embedded at the end of the document,
does two things:
1. Checks to see if the last record in the file has been read.
2. Forces the document to be printed again, using data from the next record,
when more records remain in the file. When the last record has been read,
EOF? ends the printing operation.
The EOF? instruction is the only indication in a document that more than one
copy of the document will be printed. The RC instruction can be used to start at a
record other than the first record, and the EOF? instruction forces the computer
to the next record after the document is printed.
FLD
Used to print the contents of a file manager field anywhere in a word processor
document. You must include the field number in the FLD (FieLD) instruction.
The printer gets the contents of the specified field from the current record in the
current file manager file. Only the contents of the field are printed. If you want to
print the field name, use the TTL instruction.
If the specified field for the current record is empty, a colon is printed in place
of the field contents.
