Available memory

[hilbert]

In MathCad, APPENDPRN, READPRN and WRITEPRN all require that the entire file used must fit into available memory.

My need is to use MathCad to access, create, modify and read individual records from ASCII/BINARY files that are too big to fit into available memory.

In Basic or C such ability is available using code such as:

OPEN "myfile.dat" AS RANDOM

then
WRITE "myfile.dat", Record# , Data
OR
READ "myfile.dat", Record#
