Updating Ct1S Each time you respond to this message, VSAt1GEN checks that a module with that name already exists on the A-disk, erases any old text file with that name, renames the current text file to fn TEXTOLD, and reads
the new text file in and writes it on the CMS A-disk. When the new text
file replaces the old, you receive the message: DMSVGN367I 'fn TEXTc WRITTEN ON DISK 'A'. You will receive message DMSVGN365R again; either enter the name of the
next text file you want to update, or enter END. When all the hew text files are written to the CMS A-disk, you
