Module 9245 Read a field from a table
The module reads a data field from a table opened before by Module 9240 in
"record-oriented" mode into a string. The data field is addressed by the field
name and the line number.
To maintain a high processing speed, multiple lines should be read in
ascending order.
Pay attention to the upper/lower case of field names.
If an error occurs, the content of the target string is undefined.
The module provides the contents as a string.
Call:
PS D <File handle>
from Module 9240
PS B/W/D/K <Line>
0 to 65 535
PS B/W/D/K/S<String number, column name>
0 to 15
PS B/W/D/K/S<String number, result>
