`write, f, expr1, expr2, .., exprN` | writes the exprI to file f
`write, expr1, expr2, .., exprN` | writes the exprI to terminal
`swrite(expr1, expr2, .., exprN)` | returns the exprI as a string
The `swrite` function returns an array of strings - one string for each line that would have been produced by the `write` function. The exprI may be arrays, provided the arrays are conformable. In this case, the exprI are broadcast to the same length L, then the `write` is applied as if called L times, with successive elements of the exprI written on each call. Both functions accept an optional `format` keyword. Write format strings in Yorick have (nearly) the same meaning as the format strings for the ANSI stacndard C library `printf` routine. In brief, a format string consists of: characters other than `%` which are copied directly to output conversion specifiers beginning with `%` of the general format `%`FW.PSC where: F is zero or more of the optional flags `-` (left justify), `+` (always print sign), (space) (leave space if +), `0` (leading zeroes) W is an optional decimal integer specifying the minimum number of characters to output .P is an optional decimal integer specifying the number of digits of precision S is one of `h`, `l`, or `L`, ignored by Yorick C is `d` or `i` (decimal integer), `o` (octal integer), `x` (hex integer), `f` (fixed point real), `e` (scientific real), `g` (fixed or scientific real), `s` (string), `c` (ASCII character), or `%` (the `%` character - not a conversion) For example, `> write, format=" tp %7.4f %e\n", [1.,2.], [.5,.6]` `tp 1.0000 5.000000e-01` `tp 2.0000 6.000000e-01` `>`
