Conversion of a REAL value corresponding to the setting in machine data
MD10751 $MN_SPRINT_FORMAT_P_DECIMAL into a string with:
• an integer number of <m> + <n> places or
• a decimal number with a maximum of <m> pre-decimal places and precisely
<n> decimal places.
Just the same as for the format description %.<n>P, the complete string is saved in
the character code defined by MD10750 $MN_SPRINT_FORMAT_P_CODE.
Conversion for MD10751 = 0:
The REAL value is converted into a string with an integer number of <m> + <n>
places. If required, decimal places are rounded-off to <n> places or filled with 0.
The missing pre-decimal places are filled with spaces. The minus sign is attached,
left-justified; a space is entered instead of the plus sign.
Example:
N10 DEF REAL REAL_VAR=-123.45
N20 DEF STRING[80] RESULT
N30 RESULT=SPRINT("PUNCHED TAPE FORMAT:%5.3P",REAL_VAR)
Result: The character string "PUNCHED TAPE FORMAT:-xx123450" is written to
the string variable RESULT ("x" in the example represents spaces).
Conversion for MD10751 = 1:
The REAL value is converted into a string with a decimal number with a maximum
of <m> pre-decimal places and precisely <n> decimal places. Where necessary,
the pre-decimal places are cut-off and the decimal places are rounded-off or filled
with 0. If <n> is equal to 0, then the decimal point is also omitted.
Example:
N10 DEF REAL REAL_VAR1=-123.45
N20 DEF REAL REAL_VAR2=123.45
N30 DEF STRING[80] RESULT
N40 RESULT=SPRINT("PUNCHED TAPE FORMAT:%5.3P VAR2:%2.0P",
REAL_VAR1,REAL_VAR2)
Result: The character string "PUNCHED TAPE FORMAT:-123.450 VAR2:23" is
written to the string variable RESULT.
Inserting a string.
Example:
N10 DEF STRING[16] STRING_VAR="ABCDEFG"
N20 DEF STRING[80] RESULT
N30 RESULT=SPRINT("CONTENT OF STRING_VAR:%S",STRING_VAR)
Result: The character string "CONTENT OF STRING_VAR:ABCDEFG" is written
to the string variable RESULT.
Inserting a string with a minimum of <m> characters. The missing places are filled
with spaces.
Example:
N10 DEF STRING[16] STRING_VAR="ABCDEFG"
N20 DEF STRING[80] RESULT
N30 RESULT=SPRINT("CONTENT OF STRING_VAR:%10S",STRING_VAR)
Result: The character string "CONTENT OF STRING_VAR:xxxABCDEFG" is
written to the string variable RESULT ("x" in the example represents spaces).
Inserting <n> characters of a string (starting with the first character).
Example:
N10 DEF STRING[16] STRING_VAR="ABCDEFG"
N20 DEF STRING[80] RESULT
N30 RESULT=SPRINT("CONTENT OF STRING_VAR:%.3S",STRING_VAR)
Result: The character string "CONTENT OF STRING_VAR:ABC" is written to the
string variable RESULT.
