CONCAT - move character substring (obsolete).

(obsolete - use F77 string operators)

Usage:

Where:

outstr: is a character variable that is to be copied into.
outpos: is an integer expression which gives the first character in "outstr" to be overwritten.
instr: is a charcacter expression that characters are to be copied from.
inpos: is the position in "instr" to start the copy.
nchars: is the number of characters to copy.

Description:

CONCAT copies "nchars" characters starting at character "inpos" in "instr" to character "outpos" in "outstr". The left most characters in "instr" and "outstr" are numbered 1.
