Question:

Can I write a TAB character to a file using the ME command ?
    
Answer:

Yes, this actually can be done using the new SET operator CHR n that was added in version 15.46 to return the character with ASCII value n. The following commands writes the file TABSEP.TXT containing "TAB" and "SEP" separated by a TAB character.

VARIABLE TAB
SET TAB=CHR 9
ME (REPORT) TABSEP.TXT
ME TAB{TAB}SEP
ME (REPORT) OFF
