Here is my code to search for a string if user places the cursor under the string to be searched and press PF4 the cursor will go to first occurrence and when I press PF5 it go through the subsequent occurrences.
| Code: |
/*REXX*/
ADDRESS ISREDIT 'MACRO' /* INVOKING THE MACRO */
RCODE = MAIN_PROGRAM()
EXIT RCODE
/* MAIN FUNCTION */
MAIN_PROGRAM:
ISREDIT "(THELINE) = LINE .ZCSR"
"ISREDIT (R1,C1) = CURSOR"
STRING = GET_STRING(THELINE,C1) /* CALLING FET STRING FUNCTION */
IF STRING = '*' THEN
"ISREDIT F ALL '*'"
ELSE IF STRING = '"' THEN
'ISREDIT F ALL """'
ELSE IF STRING = "'" THEN
"ISREDIT F ALL '''"
ELSE
"ISREDIT F ALL "STRING""
RETURN 0
/* FUNCTION TO GET STRING TO BE SEARCHED */
GET_STRING:
PARSE ARG DATA,COL
FLAG = 'N'
BACK = COL
FWD = COL
FNDSTR = ' '
CHECK = 'N'
SELECT
WHEN SUBSTR(DATA,BACK,1) == '+' |,

Now how can I make the cursor go back to the initial position when I press another key. |
