strdelete
Usage
strdelete (s, p, n)
Parameters
s A string variable.
p An integer expression representing the starting index of the
deletion.
n An integer expression representing the number of characters to
be deleted.
Description
The procedure strdelete (s, p, n) deletes n characters from s starting at
component s [ p ] , and the current length of s is updated to the length
of s-n . It is an error if n+p-1 is greater than the current length of s .
Example
VAR
uncensored, censored: string[80];
BEGIN
.
uncensored:= 'Attack at 6 a.m.!';
strdelete(uncensored,7,strlen(uncensored)-7);
censored:= uncensored; { censored is 'Attack!'. }
.
.
END.
strinsert
Usage
strinsert (s1, s2, p)
Parameters
s1 A string expression.
s2 A string variable.
p An integer or an integer expression representing the offset in
s2 where insertion begins.
Description
The procedure strinsert (s1, s2, p) inserts string s1 into s2 starting at
s2 [ p ] . Initially, s2 must be at least p -1 characters in length, or it
is an error. The resulting string may not exceed strmax (s2) . The
current length of s2 is updated to strlen (s1) + strlen (s2) .
Example
VAR
remark: string[80];
BEGIN
.
remark:= 'There is missing!';
strinsert(' something',remark,9);{ remark is 'There is something missing! }
