text
Data in text columns are represented by integer values.
Before you can use these in your program you must convert them
to characters in character variables.
The subroutine
strasc@"STRASC"
<"CALL STRASC(" <string>, <tuple> "("<pos>")", <len> ")"
converts a text column at <tuple>"("pos")" of length <len> characters
into a character string in <string>, type CHARACTER.
To move characters back into the tuple use the inverse subroutine
asctxt@"ASCTXT"
<"CALL ASCTXT(" <tuple>"("<pos>")," <len>, <string> ")"
which moves the characters in <string> into the tuple at <pos>,
length <len>.
