Description

Prints at k-rate using a printf() style syntax. This opcode prints at every cycle, possibly multiple times per cycle. Used inside an if-block it can behave like printf, printks (when used together with metro) or printks2 (when used with changed).

Syntax

printsk "string", [, xval1] [, xval2] [...]

Initialization

"string" -- the text string to be printed. Can be up to 8192 characters and must be in double quotes.

Performance

xval1, xval2, ... (optional) -- The k-rate values to be printed. These are specified in “string” with the standard C value specifier (%f, %d, %s etc.) in the order given.

Print Output Formatting

All standard C language printf() control characters may be used. For example, if kval1 = 153.26789 then some common formatting options are:

For more information about printf() formatting, consult any C language documentation.

Examples

Here is an example of the printsk opcode. It uses the file printsk.csd.

instr 2
  ; println is similar to printsk but appends a new line
  k0 = 0
  while k0 < 20 do
    if k0 % 2 == 0 then
      println "k0 = %d", k0
    endif
    k0 += 1
