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.
What kind of sound does x make? It depends. If the 'X' is at the beginning of a word, it makes the zzz sound (as in xylophone) or a sound kind of like eggs (as in Xavier). However, if it is preceded by vâ¦owel, it makes the -cks sound. In Xerox it makes both the z and a cks sound.
