This process was sometimes called linkage editing and the output known as a load module. A compiler works with what are sometimes called 3GL and higher-level languages. An assembler works on programs written using a processor's assembler language.
In general, however, when between vowels (as in exactamente) the Spanish x is pronounced like the English ks sound but softer or less explosive. When it comes before another consonant (as in expediciÃ³n), it has the s sound in some regions/countries but the soft ks sound in others.
The \k\ sound is sometimes spelled with qu in words of Spanish origin. This is especially true when the vowel sound that follows is long a (\Ä\), long e (\Ä\), or short i (\i\). Quesadilla and conquistador (in its pronunciations with and without the \s\ sound) are examples from our list.
