The ":set" command only takes a literal value after the equal sign, not
a variable and not an expression. Here you're telling Vim to set 'lines'
to the value "mylines" (not the value of the mylines variable) which is
illegal for that numeric option.
The following ought to work:
if $VIM_LINES != ""
let &lines = $VIM_LINES
endif
if $VIM_COLUMNS != ""
let &columns = $VIM_COLUMNS
endif
see :help :let-option
Alternately, you could also, in bash,
export VIM_POSIX=1
export LINES=60
export COLUMNS=80
vim
or in cmd.exe,
set VIM_POSIX=1
set LINES=60
set COLUMNS=80
vim
(In POSIX mode, $LINES and $COLUMNS override what system-specific
commands tell Vim about the size of the terminal: see ":help cpo-bar"
which is the last of the POSIX flags in 'cpoptions'.)
Best regards,
Tony.

And he makes no friends of sorrows.
He'll tread his galloping rigadoon
In the pathway or the morrows.
He'll live his days where the sunbeams start
Nor could storm or wind uproot him.
My own dear love, he is all my heart --
And I wish somebody'd shoot him.
