Format Specifications - IBM 5100 Basic Reference Manual

Format Specifications
For each occurrence of the pound sign (#) in an image statement, a single space is
reserved in the display or print line for a character in the correspohding expression
of the associated PRINT USING or MAT PRINT USING statement. The pound
sign represents either character or arithmetic data. For arithmetic data, decimal
points and the plus and minus signs, like the characters in the general format descrip-
tion, are printed as entered, provided the values are appropriate to the specified signs.
(See Conversion of Data Reference Values for a discussion of the displaying/printing
of signs in the image statement.) For character data, the character string will over-
ride any format descriptors.
The various format specifications are:
• Character-Format - One or more
#character~,
as shown:
####
• I-Format (integer format) - An oPtional sign followed by one or more # char-
acters, as shown:
[+
-l # [#J...
• F-Format (fixed-decimal format) - An oPtional sign followed by either:
1. No # characters, a decimal point, and one or more # characters, as shown:
.# [###l
2. One or more # characters, a decimal point followed by no # characters,
as shown:
# [###].
3. One or more # characters, a decimal point, and one or more # characters,
as shown:
[+-l [#]. .•• #[#]. ... [#]. ..
• E-Format (exponential format) - Either the 1- or F-format (described previously)
followed by four
I
characters
(1111).
The following rules define the start of a format specification:
1. A # character is encountered and the preceding character is not a # character,
decimal point, plus sign, or minus sign.
2. A plus or minus sign is encountered, followed by:
a. A # character, or
b. A decimal point that precedes a # character.
3.
A decimal point is encountered, followed by a # character and:
a. The preceding character is not a # character, plus sign, or minus sign, or
b. The preceding character string is an F-format specification.
