PARSE string,WITH,str1,str2,str3,...[,SEP='character'][,SEPMODE=M/S]
string is divided in its words, that are put in str1, str2, etc.; separation character is blank, and can be changed using SEP= with the new character enclosed in quotes.
SEPMODE= change the parsing mode of this instruction: with SEPMODE=M (Multiple, the default) more sequenced separation characters are considered separing only two words (this is ordinary if space is the separator); with SEPMODE=S (Single) a separation character is ever between two words; so two or more sequenced separation character are dividing one or more empty words; an empty word in Hilmas is a string filled with spaces. SEPMODE=S can be used with SEP=',' to read and separe a typical parameter string used in JCL, where separator is comma and where ',,' denote a skipped positional parameter.
The parsing rules are:
- if words inside string are more then strings variables specified in PARSE, in the last string variable there are all the remaining words
- if you want skip a word in a certain position, use a point (.) in the place of a string variable; for example:
PARSE instring,WITH,str1,.,str3,str4to skip the second word that is lost- If input words are greater then corresponding string variables, words are truncated without notices, as well as every move between strings.
