$$Declaring Base Variable


DECL/CHAR,100,str1,str2

str1=ASSIGN/'My full String'

$$Reading the word from char #4 to char #7


str2=ASSIGN/SUBSTR(str1,4,7)

• This is used to read a string “char by char”:
  

$$Declaring Base Variable


DECL/CHAR,100,str1,str2,char_list[15]

DECL/INTGR,len_string,i

str1=ASSIGN/'My full String'

len_string=ASSIGN/LEN(str1)

$$Loop to read single char


DO/i,1,len_string

str2=ASSIGN/SUBSTR(str1,i,i)

char_list[i]=ASSIGN/str2
