modhist modhist iname oname inserts an Author/Modification History block following the first "!--" tag in an sqr file. If the file already contains "! Author" or "! Modification History" on the first line following the "!--" tag (and is not a blank comment line), an Author/Modification History block is not inserted. The template for the Author/Modification History block is obtained from a file. The name of the file is obtained by first checking the environment variable SQRSH_MODHIST. If this is not found it looks for the environment variable SQRSHDIR and appends the name 'modhist.txt'.
