Usage: ampl [options] [file [file...]]
No file arguments means read from standard input, as does - by itself.
Options:
-Cn {0 = suppress Cautions; 1 = default; 2 = treat as error;}*
-Ln {0 = treat linear definitional constrs and var = decls as nonlin}*
-P {skip presolve -- same as "option presolve 0;" }
-S {substitute out definitional constraints (var = expression)}*
-T {show genmod times for each item}*
-enn {exit (if nn > 0) or abort command at |nn|-th error; 0 = no exit}*
-f {do not treat unavailable functions of constant args as variable}*
-g {run in a separate process group}
-ix {import functions from x; specify -i? for details }
-ooutopt {specify -o? for details}*
-s[seed] {seed for random numbers; -s means current time}*
-t {show times}*
-v {show version and license details; -v? shows other -v options}
--version {show version and exit, ignoring license files}
-xnn {allow nn wall-clock seconds of execution time}
-?? {show debug and obscure options}
* Equivalent option settings:
-Cn option Cautions n; -Ln option linelim n;
-P option presolve 0; -S option substout 1;
-T option gentimes 1; -enn option eexit nn;
-f option funcwarn 1; -ofstub option outopt fstub;
-s option randseed ''; -snn option randseed nn;
-t option times 1;
