Just two comments from full length reviews at our powerful and virtually full implementation of Standard Pascal Th e advantages of using the Pascal language are
many, fast, sell-documenting and truly structured programming — many schools and universities insist on a good knowledge and understanding of Pascal for their

Now you can learn and use Pascal on your borne micro: HISOrt Pascal is available for a wide range of home computers, including the 48K Spectrum Ty pic ally .
compiled programs run 40 times taster than their interpreted BASIC equivalent — and sometimes up to 1,000 times faster
Hisoft Pascal supports all the Standard Pascal data structures and statements: INTEGER& REALs , CHARac ters A RRA Y & SETs , RECO RD& POINTER&

Enumerated typos, FOR D O . REPEAT U N T I L WHILE D O . CASE • O F and many pRectelined Procedures arid Functions (erg SORT. TAN. SIN, COS,
