Headline => "convert to a readable string",
Usage => "toExternalString x",
Inputs => {
"x" => "any Macaulay2 object"
},
Outputs => {
String => {"a string representation of ", TT "x", ", which can be used, in conjunction with ", TO "value", ", to read the object back into the program later"}
},
"See also ", TO "toString", " which simply converts ", TT "x", " to a string that can be displayed meaningfully.",
EXAMPLE {
"toString {1,4,a,f,212312,2.123243242}"
},
EXAMPLE {
"R = QQ[x_1..x_5];",

},
"Matrices and ring elements are linearized",
EXAMPLE {
"x_1^3-3/4*x_5*x_3",
"toExternalString oo",

},
Caveat => "Not everything can be converted to a string in such a way that it can be read back into the program later.",
SeeAlso => {toString, value}
