Joel Haggar suggested I add 'cd ${PRGDIR}' below line 13 in the ma-start.sh file. Now it works. He said 'this will be included in all new releases of Mango'

$ **cat /opt/mango/ma-start.sh
**```
#!/bin/sh

Get standard environment variables

PRGDIR=dirname "$0"

#log output
exec >${PRGDIR}/logs/ma.out 2>${PRGDIR}/logs/ma.err
cd ${PRGDIR}

Only set MA_HOME if not already set

[ -z "$MA_HOME" ] && MA_HOME=cd "$PRGDIR" >/dev/null; pwd

if [ ! -r "$MA_HOME"/ma-start.sh ]; then
echo The MA_HOME environment variable is not defined correctly
echo This environment variable is needed to run this program
exit 1
fi

NONE of the help files are working. This is particularly a problem because I can't read the documentation to solve script errors due to unknown metadata script syntax changes in migrating from M2M 1.12.x to MA2.0.
